Yakagadziriswa: kuderedza mari

Deredza Sum idambudziko rakajairika rinosangana nevazhinji vanogadzira uye vanofarira zvirongwa zvakafanana. Zvinoda kunzwisisa kwakakosha kwemazano ehurongwa. Kunyange zvazvo Java ichipa nzira dzakasiyana-siyana dzekugadzirisa dambudziko iri, rinogona kuramba riri basa rinovhiringidza kune vamwe. Muchinyorwa chino, isu tichaongorora mune imwe yemhinduro dzakanyanya kushanda kune Dzikisa Sum dambudziko muJava, tichitsanangura chikamu chimwe nechimwe chekodhi nhanho-nhanho, nekudaro ichiita kuti ive nyore kunzwisisa kunyangwe kune vanotanga.

The Kuderedza Sum Dambudziko

Dambudziko rekudzikisira sum rinodzika kusvika pakupfupisa nhamba murukova rwenhamba. Dambudziko rinogona kuva nemhando dzakasiyana. Inogona kunge iri pfupiso yezvikamu zvehurongwa, zvimiro zveChinongedzoList kana kupfupisa zvinhu zveKuyerera mune akawanda-shinda nharaunda inoshandisa iyo `stream.reduce()` basa. Inoshandisa lambda mataurirwo uye anoshanda interfaces, ayo akakosha maficha eJava 8 uye pamusoro.

Java Solution

Java inopa ruzhinji rwemaraibhurari uye mabasa ekubata nyore uye kugadzirisa dambudziko. Tinenge tichishandisa Stream API yakaunzwa muJava 8. Kunyanya, iyo `reduce()` nzira inosanganisa maelementi erukova kuti ibudise muchidimbu muchidimbu.

Heino muenzaniso weJava kodhi yekuita kudaro.

public int sumOfArray(Integer[] numbers) {
    return Arrays.stream(numbers)
                 .reduce(0, Integer::sum);
}

Nhanho-ne-nhanho Tsanangudzo yeCode

Kodhi iri pamusoro inomiririra nzira inotora nhevedzano yenhamba senharo uye inodzosa nhamba yezvikamu izvi.

• Chekutanga, `Arrays.stream(nhamba)` inoshandura hurongwa kuita Rukova.
• Iyo `reduce()` nzira inobva yadaidzwa parukova urwu. Iyi nzira inotora miviri miviri: kukosha kwekutanga kwehuwandu uye nzira inoshandiswa pakuverenga huwandu.
• Kukosha kwekutanga munyaya iyi kunoiswa se'0' uye nzira inoshandiswa ndeye `Integer::sum`. `Integer::sum` ireferensi yenzira yakamira `sum` mukirasi yeInteger. Iyi nzira inodzosa huwandu hwenharo dzayo. Iri kupfuudzwa senzira yekunongedza munzira yekudzikisa.
• The `reduce()` function inobva yaita sum operation pane chimwe nechimwe chezvinhu zviri murukova uye huwandu hunodzoswa semhedzisiro yebasa racho.

Java Libraries uye Mashandiro Akafanana

Java inopa huwandu hwakakura hwemaraibhurari anogona kukubatsira kudzora uye kushanda pane hova. Mashandiro akafanana ekuti `kuderedza` anosanganisira `unganidza`, `kuverenga`, `fananidza`, `wana`, `dzokorora` pakati pemamwe, zvichienderana nekuti ndechipi chivhitivhiti chinoda kuitwa parukova.

Kuburikidza nemufananidzo uyu, isu tinokwanisa kuona kuti Java inopa ane simba uye anochinjika maturusi ekugadzirisa matambudziko akaomarara, kunyangwe senge dambudziko rekutapudza. Icho chiratidzo chekusiyana-siyana uye kusimba kwemutauro.
