Safu Tatu-Dimensional katika JavaScript
Hapa kuna mfano wa safu tatu-dimensional:
let arr = [
[
['a', 'b'],
['c', 'd'],
],
[
['e', 'f'],
['g', 'h'],
],
[
['i', 'j'],
['k', 'l'],
],
];
Ili kuchapisha vipengele kutoka kwenye safu kama hii, inahitajika kuandika mabano mraba matatu:
console.log(arr[0][0][0]); // itachapisha 'a'
console.log(arr[2][1][0]); // itachapisha 'k'
Imepangwa safu ifuatayo:
let arr = [
[
[1, 2],
[3, 4],
],
[
[5, 6],
[7, 8],
],
];
Kwa kurejea kila kipengele cha safu, tafuta jumla ya vipengele vyake vyote.
