Stack-JavaScript push / pop

I-JavaScript akusho beka, kodwa kukhona uxhaxha engasetshenziswa njengoba isitaki. Ngesikhathi esifanayo, izindlela lokusebenzisa izindlela zokwenza i-JavaScript afanayo push / pop, ungaba nezindlela isitaki, futhi amalungu afanayo siqu inhlangano yabo idatha.

Ngenxa isilinganiselo afanayo lokuqala - lena ajwayelekile futhi ethandwa isakhiwo idatha. Kodwa ukusebenza nabo njengoba isitaki ibanika hhayi kusengaphambili ukuthi kungenzeka i-syntax ulimi. Ukungeza / nokusula nge-JavaScript push / pop ukuqeda noma unshift / shift phezulu elula nje kuphela, kodwa futhi ezisebenzayo.

Ukusebenzisa izindlela

Amalungu afanayo kungenziwa agcwaliswa oluxube ezintsha usebenzisa push indlela. Waba yini umphumela walesi indlela inombolo entsha izici afanayo. Inqubo reverse - indlela pop alinaso imingcele, kodwa linikeza njengoba umphumela we-elementi lokugcina afanayo.

Njengoba ulandela ezivela olimini-syntax kanye logic afanayo bangasebenza yiluphi uhlobo idatha.

I-JavaScript push into - umbhedo noma intuthuko?

ulimu akuyona kunabayeni ngaphezulu ozakwabo "khulula" maqondana izinhlelo into-ngamakhasimende, okungukuthi, okufanayo kwenza kube nokwenzeka ukudala izinto. Ngakho elisemqoka elisho into ephathelene PLO has.

Ngokuvamile, yokuthi zikhona ku-JavaScript, kuze kube manje ngeke ilunge ukuthi iyishaye uneminye "khulula" ezivela olimini lesiphequluli. Lasekuqaleni kakhulu - ukudalwa into lapha - kuba izandla uMklami, eziqala igama into sika.

izindlela i-JavaScript pop & push uma usebenzisa izinto unika program ikhono ukudala into multi-functional ngomqondo ongokoqobo yegama elithi.

Ngokwesibonelo, ukuba Amakhasi eziningana ezihlobene kodwa ehlukene (izinto ezingenziwanga bahlobene logic of inkhulumomphendvulwano), ungakwazi ukusebenzisa umthetho ezinyakazayo kubo isivakashi. Ufaka isitaki (array) push into ikhasi isiqalo (isivakashi wafika), amnike kukhethwa senzo.

Okulandelayo ibenze phezulu ekhasini ukubeka into, okuyinto wakhethwa isivakashi. Buyisela emuva pop uyibuyisele emuva. Yisa ku - push kwesilandelayo, njalo njalo uzobe kwakhiwa ingxoxo yayo yonke ibhayisikobho isivakashi zamanje. Lokhu kungaba wusizo njengoba umthuthukisi ngokuya isipiliyoni nezibalo, futhi unikeze navigation esengxenyeni samanje kusayithi.

Isitaki, futhi amalungu afanayo yenhlangano idatha

Kukhona imisebenzi eziningi eziba umphumela kudinga ukukhetha okuningi. Uma ukhetha ukusebenzisa iqoqo uma noma icala isitatimende, uthola elikhulu, elide futhi branched izimo "ehlathini".

Ngokuvamile, akuyona isixazululo ezimbi, kodwa uma ufuna ukushintsha into, sekuyisikhathi eside ukhumbule lokho isimo kanjani, futhi i-algorithm ngeke illegible, kanye ezingemnandi neze, kungaba umthombo nzima ukubona amaphutha.

Ngosizo kwisitaki cishe kuzo zonke izimo, ungenza kube lula.

Kunenkinga: kumele ukhethe umhlinzeki kusukela emakhulwini etholakalayo. umculi ngamunye ungenza okuthile izikhundla ezintathu (kusuka eyodwa kuya kwemithathu kunoma iyiphi inhlanganisela):

• t - do nesondlo;
• s - kungaba ngokugcwele ukufeza ukulungiswa;
• i - unelungelo bazilungisele umshini iwaranti.

Ukuze ngokushesha ukhethe Order Executive nge uhlobo olufanele (uhlobo lomsebenzi), ungenza imisebenzi emithathu-JavaScript push uphinde uhlangane afanayo ku yezinhlamvu olulodwa.

Ukucinga elayinini ilandelana njalo kusobala kakhulu izimo eziningi. Yisimo okulula amathathu mhla ezintathu kukho kuphela, kodwa ngisho lapha kuzoba ikhodi eziningi ngaphezu e ngokuqhathanisa imigqa emibili kuphela.
