matrix.js
Write and export rotateLeft() and rotateRight() functions that rotate the matrix to the left (counterclockwise) and to the right (clockwise) respectively.
- Matrix is implemented via array
- Functions should return a new matrix without changing the initial one
Examples:
const matrix = [
[1, 2, 3, 4],
[5, 6, 7, 8],
[9, 0, 1, 2],
];
rotateLeft(matrix);
// [
// [4, 8, 2],
// [3, 7, 1],
// [2, 6, 0],
// [1, 5, 9],
// ]
rotateRight(matrix);
// [
// [9, 5, 1],
// [0, 6, 2],
// [1, 7, 3],
// [2, 8, 4],
// ]
