Huānga - he ... He kupu whakataki poto ki te kaupapa

Tangata e kua ako hōtaka i te whare wānanga e mohio e ngā kaiako ahu ki te hoatu anake te taketake, rauemi taketake mō rātou ngā ākonga. Kei te whakaaro ano hoki ngā huānga Kaupapa, engari i roto i te akoranga i muri mai. Te aha? No te mea huānga - ko te turanga e taea ai te kaihātepe ki te mahi ki te pukapuka nui o ngā mōhiohio.

whakataki

kaupapa o teie mahana, tīmata tatou ki te meka e whakamōhio tatou i te whakamāramatanga o taua wā. Huānga - nga mea timatanga papatono taiao, e tohu ana i te huinga o ngā raraunga i roto i te puka ripa rārangi ranei. A feruri na i te raupapa o ngā tau tupurangi 1, 6, 2, 4, me 8. e te reira ngohi. Ia tau i tuhituhia i roto i te rarangi, kua ona ake tau rangatū, me e he he aha hanga reira taea ki te pā (kawe) ratou ki te ngohi o te hōtaka.

record

Fakakaukau ki he founga e tuhia te huānga i roto i te mahi. Record, huānga tohu - kua hanga reira ki te tohu i to ratou momo hōtaka (ka e uara e penapena i roto i te ngohi) me te maha o ngā pūtau. I te tahi taime hötaka hanga ngohi nui, kahore e tautuhi ana i te maha tangohia o ngā huānga, engari ka uru koe i te reira i koe ki te kia tupato e kore e fuu te hōtaka, me te tīmata kōrero ki ngā pūtau kau.

• D: ngohi [1..k] o tūturu; - na tuhi i te ngohi ki "Pascal". Ki te whai koe ki te waihanga mohio te hōtaka e ka whai koe i te mōrahi o te 5 huānga, ka taea e koe te whakamahi i te tomokanga D: ngohi [1..5] o tūturu;

Ka rite ki ai koe i fifili D - ko te pukapuka, te tikanga i te ingoa o te ngohi; tūturu - Ko te momo (hōputu) o te raraunga e kia roto ai i roto i te ngohi tenei; ngohi [] - Ko te maha o ngā huānga ngohi.

pīra

I roto i te tikanga ki te mahi ki te huānga o te ngohi, ko reira e tika ana ki te tono i te hōtaka. Huānga - ko te taua tau ranei kupu, kia rite ki tetahi atu enei. I roto i te tikanga ki te mahi ki te huānga ngohi, ko reira e tika ana ki te whakauru: D [1]. Tenei ka tīpako i te āhuatanga tuatahi o te ngohi, me te ki te whakahaere ngā mahi ki a ia. Hei tauira:

• tā (D [1]); - Tenei whakahau e taea ai te kaiwhakamahi ki te whakaatu i te uara roto i roto i te pūtau tuatahi o te ngohi.

E tano ia tapao e te mea e haere ana koe ki te kawe i roto i ngā mahi pāngarau ki ngā huānga, ka kia utu koe whakarongo ki te momo. Ka taea e te mahi koe i tenei anake, ki te whai koe i te ngohi o ngā tau. Hei hanga i mārama ai:

• Ki te whai koe i te ngohi o te D: ngohi [1..k] o kuputuhi; - a roto i te pūtau D [1] = 1, ka koe e taea e kore te whakamahi i tenei huānga i roto i ngā mahi pāngarau no te hōtaka mo te "1" - ko noa tenei te kupu "tetahi", e kore te tau. Na mataara taurangi, me o ratou momo.

Ki te whakamahere koe ki ngā mahi pāngarau, i roto i te ngohi tika i ki kia penapena tau pai obespokoytes tona momo i roto i te mua, me te tautapa i te "tūturu" ranei "tau tōpū" ranei.

ripanga

Kia inaianei kōrero a pā ana ki te wāhi huri noa tatou. Te ora nei tatou i roto i te ao e toru-ahu, me te nuinga o nga taonga e taea te whakaahuatia ki 3 tawhā: roa, te whanui, teitei. A i reira nga huānga taha. huānga e rua-ahu - he tepu ki raraunga, i roto i nei whakawhiwhia ia huānga te neke atu i te kotahi tau rangatū, me te rua - te tau aho, me te tīwae tau. A, no te faahiti ki te ngohi e rua-ahu me whakapūtā e rua te maha - D [1, 1].

Fakatatau ki ai, ka e taea ki te rokiroki nui o ngā raraunga tenei ngohi. Kia aroha mai, i roto i te reo hōtaka pakeke, i roto i te nuinga o te wā, te tau huānga ngohi e taea te mahi ngā tau anake. Na reira, ko te rokiroki o papa nui, riro te reira rawa raruraru e tika ana ki te meka e ka whai ia tīwae o te tepu, ki te waihanga i tētahi ngohi motuhake.

Hei tauira, whakaaro to tatou he tepu i roto i nei raraunga Kua oti te tuhituhi ki te ākonga. Ko ratou: tau o whanau, te ingoa o te piha haapiiraa.

I raro i huru noa, to tatou ki te hanga i ngā huānga maha, i runga i nga hiahia rānei. Ka taea e tatou te hanga i te ngohi e rua-ahu o te momo tau ki te rā taonga o te whanau me te piha haapiiraa, a te ngohi tuarua mō te rokiroki mōhiohio kuputuhi (FI). Ko ko reira ērā. Tuatahi, te ingoa whakamutunga, me te tuatahi, kia whai koe ki te hapai i wehe. Tuarua, ka taea e koe ngāwari te tiki puputu'u ka whakakī i te ngohi ki te tau, me te piha haapiiraa. Na reira, ka waiho te reira māmā ki te hanga i 4 huānga motuhake mō ia tīwae. Whakaae, he reira rawa cumbersome?

PHP

Ka taea e ngā huānga PHP whakaoti i te raruraru rite whakahuatia i runga ake. Ko te meka ko e i roto i tenei reo hōtaka, ka taea e koe te whakapūtā te momo e kore anake o ngā raraunga i roto i te ngohi, ko te momo mita (taupū). I tua atu, kia kia roto nga raraunga o ngā momo rerekē i roto i te ngohi kotahi. Te hanga i te ngohi kotahi-ahu (ki te hiahia koe ki te tango i tetahi tīwae):

• $ Huānga = ngohi (1989, 1988, ...);

hanga ana tēnei tauira i te ngohi ohie. hanga te taupū te aunoa, me te whakaaro kore. Ko, te huānga kore ngohi - 1989, te tuatahi - 1988, me ētahi atu Ko te aha, ki te hiahia tatou ki te hoatu i te tepu katoa ki te ngohi multidimensional? He aha e maha-ahu ngohi PHP? Tenei hanganga, i roto i nei hoki ko te ngohi i ia huānga. Me pēhea te ki te wetewete i te hi'oraa mo tatou?

$ Ripanga = ngohi (

ngohi (1989, "Smith", "Hoani", 9)

ngohi (1988, "Smith", "Pita", 10),

...

);

Aha to tatou i roto i te mutunga? E tatou i mua ia tatou i te ngohi i huaina $ tepu, i te whakatau rarangi te rarangi i roto i te tepu. Ki te kovorit te ngohi o ngā huānga, na ka titiro ratou rite tenei:

• $ Ripanga [0, 0] = 1989, $ tepu [0, 1] = "Smith", $ tepu [0, 2] = "Hoani", $ tepu [0, 3] = 9.
• $ Ripanga [1, 0] = 1988, $ tepu [1, 1] = "Pita", $ tepu [1: 2] = "Pita", $ tepu [1, 3] = 10.

Ai 0 me te 3 tīwae he ngohi tau, a 1 me 2 - kuputuhi. Ki te tika, ka taea e koe te tahuri tonu te raraunga e tika ana i roto i te hōputu e hiahiatia ana, ka hanumi ngā pūtau.
