This should be the input and output:
Input: matrix = [[1,2,3],[4,5,6],[7,8,9]]
Output: [[7,4,1],[8,5,2],[9,6,3]]
The returned output is actually the same as the input. What am I doing wrong?
var rotate = function(matrix) {
let result = matrix;
let i = 0;
let index = matrix.length - 1;
for (let x of matrix) {
for (let n of x) {
result[i][index] == n;
if (i<matrix.length-2)
i++;
}
index--;
}
console.log(result);
return result;
};
var list= [[1,2,3],[4,5,6],[7,8,9]];
rotate(list);const matrix = [
[1,2,3],
[4,5,6],
[7,8,9]
];
const rotate = (m) => {
const n = m.length;
const r = [ ...m.map(a => []) ];
for (let i = 0; i < n; i++) {
for (let j = 0; j < n; j++) {
r[i][j] = m[n - j - 1][i];
}
}
return r;
}
const result = rotate(matrix);
console.log(result);
