Ungayethula kanjani isiqalo esikhulayo se-b2c ngemuva kwe-hackathon

Isibikezelo

Ngicabanga ukuthi abaningi bafundile isihloko mayelana nokuthi amaqembu asinda yini ku-hackathon.
Njengoba bebhale emibhalweni yalesi sihloko, izibalo ziyadabukisa. Ngakho-ke, ngithanda ukukutshela ngami ukuze ngilungise izibalo futhi nginikeze amathiphu asebenzayo okuthi ungashaywa kanjani umoya ngemva kwe-hackathon. Uma okungenani iqembu elilodwa, ngemva kokufunda lesi sihloko, lingayeki ukuthuthukisa umbono walo opholile ngemva kwe-hackathon, lithatha iseluleko sami futhi lidale inkampani, lesi sihloko singabhekwa njengempumelelo :)
Isexwayiso! Lesi sihloko ngeke sibe nemininingwane yobuchwepheshe yokusetshenziswa kohlelo lokusebenza. Ngizokutshela indaba yethu (TL;DR) ekuqaleni, futhi amathiphu awusizo esizifundele wona ngesikhathi sokuthuthuka anikezwa ekugcineni.

"Impumelelo" indaba

Igama lami ngingu-Danya, ngasungula i-emovi, isevisi yokukhetha amafilimu nge-emoji, ekhule ngegciwane ngo-600% kulezi zinsuku ezimbalwa ezedlule. Manje uhlelo lokusebenza lunokulanda okuyizinkulungwane ezingama-50 futhi lungaphezulu koku-2 kwe-App Store ne-Google Play. Eqenjini, ngenza ukuphathwa nokwakhiwa komkhiqizo, kanye nokuthuthukiswa kwe-Android ngaphambilini. Ngifunda e-MIPT.

Ukuzihlangula: Siyaqonda ukuthi lesi yisiqalo nje hhayi "indaba yempumelelo." Sinethuba lokuqhubeka nokukhula ngokushesha noma silahlekelwe yikho konke. Kodwa, ngokuthatha leli thuba, sinqume ukuxoxa indaba yethu yangempela, ngethemba lokukhuthaza labo abafuna ngolunye usuku ukuqalisa okwabo, kodwa abangakafiki kulokhu.

Uhambo lwethimba lethu luqale e-Finnish hackathon Junction, lapho bekunengoma enikezelwe kumasevisi amafilimu. Iqembu elivela kuPhystech lawina kuleyo hackathon; bakwazile ukwenza okwengeziwe, kodwa abazange baqhubeke nokuthuthuka umqondo. Ngaleso sikhathi, sakha umqondo - ukucinga amafilimu ngemizwa ayivusayo, sisebenzisa izithonjana. Sikholelwa ukuthi inala yolwazi mayelana nefilimu: ukubuyekezwa okude, izilinganiso, izinhlu zabalingisi, abaqondisi - kwandisa isikhathi sokusesha kuphela, futhi ukukhetha ama-emoji ambalwa kulula kakhulu. Uma i-algorithm ye-ML enquma imizwa kumafilimu isebenza kahle, futhi sisusa amafilimu umsebenzisi asewabukile, khona-ke kuzokwazi ukuthola ifilimu kusihlwa kumasekhondi angu-10. Kodwa iqiniso lalingenjalo ngaleso sikhathi, futhi ngephrojekthi enjalo thina kwenziwe.

Ngemuva kokuhlulwa e-Junction, iqembu lalidinga ukuvala iseshini, bese sifuna ukuqhubeka nokuthuthukisa iphrojekthi. Kunqunywe ukuthi kudlulelwe kuhlelo lokusebenza lweselula ngenxa yezinga eliphansi lokuncintisana uma kuqhathaniswa namawebhusayithi. Ngokushesha nje lapho siqala ukuhlangana ukuze sisebenze, kwavela ukuthi akuwona wonke amalungu eqembu alungele ukunikela isikhathi sawo samahhala sokufunda (kanye nabanye emsebenzini) ukuthuthukisa iphrojekthi ethi:

• kunzima
• umsebenzi onzima
• kudinga ukuzinikela okuphelele
• akulona iqiniso ukuthi umuntu uyalidinga
• ngeke yenze inzuzo maduze

Ngakho-ke, ngokushesha kwase kusele ababili kuphela: mina nomngane wami ovela e-Faculty of Computer Science e-Higher School of Economics, owasiza nge-backend. Ngokuqondana nje, kwakungalesi sikhathi sokuphila kwami ​​lapho ngaphelelwa khona isithakazelo emisebenzini yesayensi. Ngakho-ke, naphezu kokusebenza kahle kwami ​​ezifundweni, nganquma ukungena esikhungweni semfundo ephakeme. Benginethemba lokuthi ngizoba nesikhathi sokwethula iphrojekthi entsha phakathi nonyaka futhi ngizithole ngisemsebenzini omusha. Kuyafaneleka futhi ukuqaphela ukuthi inkinga yokuthatha isikhathi eside ukukhetha i-movie ku-Kinopoisk ibilokhu ibuhlungu kimi, futhi ngangifuna ukuyinciphisa ngokunikeza abantu indlela entsha yokukhetha.

Inselele kwaba ukwakha i-algorithm yokunquma imizwa yefilimu futhi siqoqe idathasethi, futhi ngenxa yokuthi besingenaye uchwepheshe ochwepheshile kusayensi yedatha. Futhi, njengonjiniyela, ukudala i-UX elula nentsha, kodwa ngesikhathi esifanayo i-UI enhle. Ngemva kokwenza kabusha umklamo izikhathi ezingaba ngu-10, ngagcina senginokuthile okwakunethezekile, futhi kubukeka kukuhle, ngenxa yomqondo othile wobuhle ongaphakathi. Saqala ukubhala ukusekelwa, ukuqoqa isizindalwazi samafilimu, idathasethi ebesiyidinga, futhi sakha uhlelo lokusebenza lwe-Android. Ngakho kwadlula intwasahlobo nehlobo, kwakukhona isizindalwazi samafilimu nama-API, i-MVP yohlelo lokusebenza lwe-Android yenziwa, isethi yedatha yavela, kodwa yayingekho i-algorithm ye-ML yokubikezela imizwa.

Ngaleso sikhathi, okwakulindelwe kwenzeka: umngane wami, owayesebenza ngemuva, wayengasakwazi ukusebenza mahhala, wathola itoho eYandex, futhi ngokushesha wayeka umsebenzi. Ngasala ngedwa. Engakwenza kulezi zinyanga eziyisithupha kwaba ukuqala kanye nokufundisa itoho. Kodwa angizange ngimshiye futhi ngaqhubeka ngihamba ngedwa, ngesikhathi esifanayo nginikeza ukusebenza kule phrojekthi nge-DS ehlukahlukene evela ku-Faculty of Computer Science, kodwa akekho owayenesisusa sokusebenza mahhala.

NgoSepthemba ngaya ePhystech.Start, lapho ngingamukelwanga khona, kodwa lapho engahlangana khona nabasunguli bami bamanje. Ngemva kokukhuluma ngale phrojekthi, ngaqinisekisa abafana ukuba bahlanganyele nami. Ngakho, ngaphambi kuka-October hackathon Hack.Moscow, sasisebenza umsebenzi wesikhathi esigcwele. Senze inguqulo ye-iOS yohlelo lokusebenza, futhi sabhala i-algorithm eyinhloko esebenzisa i-NLP ukucacisa imizwa kumafilimu. Vuliwe Hack.Moscow size nephrojekthi esenziwe ngomumo (ithrekhi ivumele lokhu, yayibizwa ngokuthi “Ithrekhi yami”) futhi yasebenza kuphela esethulweni amahora angama-36. Ngenxa yalokho, siphumelele, sathola impendulo enhle evela kubaluleki, futhi samenywa ukuba I-Google Developers Launchpad ngoDisemba futhi bakhuthazeke kakhulu.

Ngemuva kokugebenga, umsebenzi waqala ngo-24/7 kumkhiqizo ngaphambi kwe-Launchpad. Sifike kukho ngomkhiqizo oqediwe, i-beta esebenzayo ku-Android kanye ne-alpha ye-iOS, kanye nomsunguli omusha ovela ku-Faculty of Computer Science of the Higher School of Economics, owangishintsha wafaka i-backend, njengoba ngangingakwazi. qhubeka nokwenza i-Android, ukusekela, ukuklama nokucabanga ngakho , yini enye abasebenzisi abayidingayo emkhiqizweni. Kwa-Launchpad, sithuthukiswe kakhulu ekukhangiseni nasekuphathweni kwemikhiqizo. Ngenyanga siqede konke ebesikufuna, sakhululwa futhi... akwenzekanga lutho.
Uhlelo lokusebenza ngokwalo aluzuzanga lutho, nakuba kwakubonakala ngathi kufanele (sisanda kwenza izincwadi ezinkundleni zokuxhumana, i-Pikabu kanye neziteshi ezimbalwa ze-telegram).

Lapho ukudumala kokuqala kokungaqondi kwethu kudlula, saqala ukuhlaziya ukuthi yini eyayingahambi kahle, kodwa konke kwakunjengoba kufanele kube njalo, ngoba ngaleso sikhathi sasingazi lutho ngokumaketha kanye ne-PR, futhi umkhiqizo wawungenazo izici zegciwane.

Njengoba cishe yayingekho imali, sisindile ekukhangiseni okushibhile kumakhasi omphakathi e-VK, okusigcine sikhula ngokufakwa okungu-1K ngesonto. Lokhu kwanele ukuhlola imibono yomkhiqizo kulezi zithameli futhi ngesikhathi esifanayo ubheke ukutshalwa kwezimali, usujwayelene neningi lemboni yemali yaseMoscow ngokusebenzisa izinkundla nezingqungquthela ezihlukahlukene. Saya ku-accelerator ye-HSE Inc, lapho sasebenza khona ngomkhiqizo, ukuthuthukiswa kwebhizinisi kanye nokuheha abatshalizimali, futhi ngaphezu kwalokho sathatha isifundo esithi “Uwenza Kanjani umkhiqizo?” Umsunguli wePrisma and Capture, u-Alexey Moiseenkov, okusisize ngempela ukuqonda. okumele ukwenze ngokulandelayo. Kodwa izinto bezingahambi ngendlela ebesingathanda ngayo: ukukhula bekukuncane, futhi i-Data Scientist yethu yaqala ukusebenza... qagela kuphi?
- Yebo, ku-Yandex!
- Ngubani?
- Umkhiqizo.

Cishe sakha isigaba esisha emkhiqizweni ohlobene nevidiyo, sabamba iqhaza ekuheheni abatshalizimali, okusisize ukuthuthukisa ukuqonda ngemakethe yokusakaza, imodeli yebhizinisi kanye nombono. Ngifunde ukudlulisa lokhu kubatshalizimali ngamazinga ahlukahlukene empumelelo, kodwa ngaphandle kwalokho kwakungekho ukuthuthuka kwangempela okubonakalayo. Kwakukhona ukholo kithina kuphela nasekuqondeni kwethu ukuthi akekho owayexazulule inkinga yokukhetha ifilimu emakethe yaseRussia ezinkonzweni zamahhala. Ngalesi sikhathi, imali isiphelile, saqala ukuzibandakanya ekukhangiseni okungabizi kakhulu, okwaletha okuncane kakhulu. Kwakunzima kakhulu, kodwa ukholo nokugxila ngamaphesenti ayikhulu kwangisindisa. Ngesikhathi se-accelerator, sasixhumana ngenkuthalo nochwepheshe abahlukahlukene kanye nabatshalizimali, futhi sathola impendulo eminingi - hhayi ngaso sonke isikhathi emihle. Sizwakalisa ukubonga kwethu kubo bonke abafana abavela kwa-HSE Inc ngokusisekela ezikhathini ezinzima. Njengabasunguli, sayiqonda imininingwane yesiqalo futhi sakholelwa ukuthi akukho okulahlekile okwamanje.

Sabe sesibhala kuPikabu sabe sesihamba negciwane. Ngokuyisisekelo, umsebenzi oyinhloko bekuwukuthola abasebenzisi abaludinga ngempela uhlelo lwethu lokusebenza; baphenduke abafana abavela kuchungechunge lwe-"Seriaomania" ku-Pikabu. Babe ngabokuqala ukubamba igagasi, bathanda futhi babelana kakhulu, basiletha ku-"Hot" futhi saba nezinkinga kuphela ngamaseva...

Sifinyelele phezulu kwe-Play Market ne-App Store, sathola ukubuyekezwa kwe-600, sawa futhi savuka, futhi ngesikhathi esifanayo sabhala ukukhishwa kwezindaba ezincwadini futhi sanikeza izingxoxo ... Sibonga ngokukhethekile kumphakathi omkhulu we-hackathon Abaduni baseRussia, lapho abantu abasisiza khona ukuxazulula izinkinga zobuchwepheshe mahhala.

Kusihlwa, i-hype yase idambile, amaseva asebenza ngokujwayelekile, futhi sase sizolala ngemva komjaho wamahora angu-20, lapho kwenzeka okumangalisayo. Umphathi womphakathi we-NR Community usithandile isicelo sethu futhi wathumela mahhala ngathi eqenjini lakhe labantu abayizigidi ezingu-5 ngaphandle kolwazi lwethu. Iziphakeli zingawuphatha kangcono umthwalo, kodwa sisachitha isikhathi sethu esiningi sithuthukisa.

Kodwa, njengoba i-YCombinator isho, uma amaseva akho ephahlazeka, lokho kusho ukuthi kuyimpumelelo (bacaphuna i-Twitter njengesibonelo). Yebo, kungaba ngcono uma silungiselele umthwalo onjalo kusengaphambili, kodwa asizange silungiselele impumelelo enjalo ngemva kwalokhu okuthunyelwe.

Okwamanje sinesipho esivela kumtshali-zimali, futhi sizothuthukisa ngokuqhubekayo. Umgomo wethu omkhulu uwukucwenga umkhiqizo ukuze uvumelane neningi labasebenzisi bethu.

Manje ake siqhubekele kumathiphu. Ithimba lethu likholelwa kakhulu emaphutheni osindile futhi likholelwa ukuthi iseluleko esifana nokuthi “Yenza A, B, no-C” asilusizo. Vumela abaqeqeshi bebhizinisi bakhulume ngalokhu. UPeter Thiel wabhala kwethi “Zero to One”: “U-Anna Karenina uqala ngamagama athi “Yonke imindeni ejabulayo ijabule ngokulinganayo, yonke ayijabule ngendlela yayo,” kodwa mayelana nezinkampani kuphambene ncamashi. Indlela yenkampani ngayinye ihlukile, futhi akekho ongakutshela ukuthi lenza kanjani ibhizinisi lakho. Kodwa! Bangakutshela ukuthi yini ngempela ongayenzi. Sawenza ngokwethu amanye ala maphutha.

Amathiphu

• Ngenxa yokuncintisana okuphezulu nezinkampani ezinkulu, ukuqalisa kwe-b2c kudinga umkhiqizo wekhwalithi ephezulu, okunzima kakhulu ukuwusebenzisa ngaphandle kwesipiliyoni ekudaleni imikhiqizo ye-b2c, ngaphandle kwabantu abazimisele ukuzinikela kulokhu unyaka mahhala, noma ukutshalwa kwezimali kwezingelosi ezikunikezayo. , okokuqala, isikhathi. Kuyadabukisa ukusho lokhu, kodwa ukuthola ukutshala izimali zezingelosi ze-b2c eRussia ngaphandle kokukhula noma isipiliyoni esibanzi cishe akunakwenzeka, ngakho-ke uma unemibono mayelana namathuba e-b2b, kungcono ukwenza i-b2b eRussia okwamanje, ngoba imali yakho yokuqala kwenzeke ngaphambili.
• Uma usanquma ukwenza i-B2C ngaphandle kwemali, inkinga oyixazululayo kufanele kube eyakho. Uma kungenjalo, ngeke ube namandla anele nesifiso sokuwuqeda futhi ugqugquzele iqembu lakho.
• Uma, ngemva kokukhuluma kwakho (cishe izethulo kubatshalizimali), iphrojekthi yakho ithola impendulo embi kakhulu, khona-ke kukhona izinketho ezimbili: kufanele ulalele ngempela futhi wenze i-pivot, noma imakethe ivele ingakuqondi, futhi uthole ukuqonda abaningi abangakunakanga. Yilezi zinto abanye abangazinaki noma abazibheka njengezibalulekile ezisiza ezinye iziqalo zikhule ngokushesha minyaka yonke. Kuyacaca ukuthi amathuba okugcina angaphansi kwe-1%, kodwa cabanga njalo ngekhanda lakho ngemva kokulalela wonke umuntu, futhi wenze lokho okholelwa kukho, ngaphandle kwalokho awusoze wakuthola ukuqonda okunjalo.
• Yingakho umbono ungafaneleki lutho, ngoba uma kuwufanele okuthile, khona-ke u-1% kuphela ozokholelwa kuwo, futhi u-1% wabo uzoqala ukukwenza. Umbono omuhle ofanayo ufika kubantu abangaba yi-1000 ngesikhathi esisodwa nsuku zonke, kodwa oyedwa kuphela oqalayo, futhi ngokuvamile akaqedi. Ngakho-ke, ungesabi ukutshela wonke umuntu ngombono wakho.
• Konke okubona kudingekile ukuthi ukwenze imibono yakho, edinga ukuthi i-KPI iziqinisekise. Isikhathi sakho kufanele sihlelwe, kufanele wazi ukuthi wenzani ngaluphi usuku, iyiphi i-hypothesis oyihlolayo kulelo sonto, uzokwazi kanjani ukuthi uyihlolile, nokuthi uyini umnqamulajuqu, ngaphandle kwalokho' uzogxila “ekwenzeni” njalo. Impendulo yakho embuzweni othi “Yini obuyenza isonto lonke” akufanele ithi “Ngenze u-X,” kodwa “ngenze u-Y,” lapho “ngenze” ngokuvamile kusho ukuhlola umbono othile.
• Ku-b2c, ukuhlola i-hypothesis yakho kungaba imikhiqizo yezimbangi kanye nemakethe (isibonelo, isevisi exazulula inkinga isivele ikhona, kodwa ungayenza kangcono izikhathi ezimbalwa), noma amamethrikhi ekuhlaziyeni umkhiqizo, njenge-Amplitude, Firebase, Izibalo ze-Facebook.
• Uma wenza i-b2c, lalela kancane kubalandeli bendlela yokusebenza ye-CustDev edumile eRussia, abayisebenzisa lapho kudingekile nalapho kungenasidingo. Ucwaningo olusezingeni eliphezulu nezingxoxo nabasebenzisi ziyadingeka ukuze kukhonjwe imininingwane, kodwa akukwazi ukuhlola ngezibalo i-hypothesis, njengoba zingezona izindlela zocwaningo.
• Tshala imali kuphela ngemuva kwe-MVP nokuhlolwa kwemibono eyisisekelo, ngaphandle uma, kunjalo, unolwazi lokuqalisa esikhathini esidlule. Uma unesiqalo se-b2c, khona-ke ngaphandle kwemali engenayo kuyoba nzima kakhulu kuwe ukuthola umtshali-zimali eRussia, ngakho-ke cabanga ukuthi ungaqala kanjani ukukhula kubasebenzisi, noma ukuthi ungaqala kanjani ukuthola imali.
• Ukuqala, okokuqala, mayelana nesivinini sokukhula kanye nokwenza izinqumo. Ezimweni zamanje zamanje zaseRussia, ukunyakaza okusheshayo kwephrojekthi ye-b2c akunakwenzeka ngaso sonke isikhathi, kodwa yenza konke ukuhamba ngokushesha. Yingakho ithimba labasunguli ngokuvamile lihlanganisa abantu abangu-2-3 abasebenza ngokugcwele, futhi ithimba labangane abayi-10 abasebenza isikhathi esithile ekuqaleni kuyiphutha elizokubulala. Abantu abaningi bazizwa bephatheke kabi ngoba kuphakama inkinga entsha: kufanele kube nomphathi wephrojekthi ohlukile owenza lokho futhi asikwe ngoba awukwazanga ukuthola abasunguli abakhuthele ngokwanele.
• Ungahlanganisi umsebenzi nokuqalisa. Lokhu akunakwenzeka futhi kuzokubulala maduze noma kamuva. Wena njengenkampani. Ngomuntu siqu, konke kungase kube "kuhle" kuwe, bazokuqasha ku-Yandex futhi uzothola iholo elikhulu, kodwa akunakwenzeka ukuthi ukwazi ukwakha into enkulu lapho, ngoba ukuqala kwakho kuzohamba kancane kakhulu.
• Ungathatheki yikho konke. Ukugxila kwamaphesenti ayikhulu kubaluleke kakhulu kuwe, ngaphandle kwalokho uzojikeleza (shintsha inkambo) izikhathi ezi-3 ngesonto. Kumele ube nesu kanye nokuqonda ukuthi yini okumele uyenze, lapho uya khona. Uma ungenayo, qala ngokuhlaziya izimbangi zakho kanye nesikhundla sabo emakethe. Phendula umbuzo othi “Kungani u-X engenzanga engifuna ukukwenza?” ngaphambi kokubhala noma yini. Ngezinye izikhathi impendulo ingase ibe “bakubheka njengokungabalulekile futhi benza iphutha,” kodwa kufanele kube nempendulo.
• Ungasebenzi ngaphandle kwamamethrikhi ekhwalithi (lokhu kumayelana ne-ML). Lapho kungacaci ukuthi yini futhi kanjani okudingeka ithuthukiswe, akucaci ukuthi yini enhle noma embi manje, awukwazi ukuqhubeka.

Yilokho kuphela. Uma ungenzi okungenani lawa maphutha ayi-11, ukuqalisa kwakho kuzohamba ngokushesha, futhi izinga lokukhula liyimethrikhi eyinhloko yanoma yikuphi ukuqalisa.

Izinto zokwakha

Njengezinto zokufunda, ngingathanda ukutusa isifundo esihle kakhulu sika-Alexey Moiseenkov, umsunguli wePrisma, esafunda kuye okuningi.

Uzokutshela ukuthi inkampani ye-IT ihlanganisani, kanjani ukusabalalisa izindima, ukubheka abasunguli, nokwenza umkhiqizo. Lena imanuwali nje "Ukwakha kanjani ukuqalisa kusukela ekuqaleni." Kodwa ukubukela izifundo ngaphandle kokuzijwayeza akusizi ngalutho. Siyibuke enguqulweni yevidiyo futhi sayithatha mathupha, ngenkathi sizilolonga ngesikhathi esifanayo.

Wonke umuntu oqalayo kufanele azi i-YCombinator - isisheshisi esingcono kakhulu emhlabeni, esikhiqize amaqembu abasunguli anjenge-Airbnb, iTwitch, iReddit, iDropbox. Izifundo zabo zokuthi ungaqala kanjani ukuqalisa, ezifundiswa eNyuvesi yaseStanford, nazo ziyatholakala ku-YouTube.

Ngiphinde ngincome kakhulu incwadi kaPeter Thiel, umsunguli we-PayPal kanye nomtshali-zimali wokuqala ku-Facebook. “Zero koyedwa.”

Senzani ngisho?

Senza uhlelo lokusebenza lweselula olusesha amamuvi sisebenzisa izithonjana ezinezincomo eziqondene nawe ezisuselwe ezilinganisweni zamamuvi. Futhi kuhlelo lwethu lokusebenza ungathola ukuthi iyiphi i-cinema eku-inthanethi ongabuka kuyo ifilimu ethile, futhi izilinganiso zomsebenzisi zicatshangelwa ekusesheni ngokomzwelo. Sikholelwe, imizwa ayibekwanga ngesandla, sisebenze kulokhu isikhathi eside kakhulu :)
Ungathola okwengeziwe ngathi ku vc.

Futhi noma ubani ofuna ukulanda, wamukelekile. Landa.

Ukuqonda okuncane nesiphetho

Ekupheleni kwesihloko, ngithanda ukuncoma ngokuqinile ukuthi ungawashiyi amaphrojekthi akho ngemuva kwama-hackathons. Uma ungenza umkhiqizo odingwa ngabantu, awusoze wephuza ukuya emsebenzini, ngoba uzosebenza izikhathi eziningi kangcono nangempumelelo kunabantu abangakaze baqale. Ekugcineni, konke kuncike ezifisweni zakho kanye nemigomo yakho ekuphileni.

Futhi ngithanda ukuphetha ngamazwi uSteve Jobs awasho kuJohn Sculley (ngaleso sikhathi oyi-CEO ye-Coca-Cola) lapho ememela ukuthi azosebenza e-Apple:

"Ingabe ufuna ukuthengisa amanzi ashukela impilo yakho yonke noma ufuna ukushintsha umhlaba?"

Ezinyangeni ezizayo sizobe sandisa ithimba lethu, ngakho-ke uma ungathanda ukusebenza nathi, thumela i-resume yakho kanye nogqozi ku- [i-imeyili ivikelwe].
