Rotate the elements in a 3-dimensional array 90 degrees to the left or to the right.
const rotateLeft = (arr) => {
let retArr = [[],[],[]]
for (let i = 0; i < arr.length; i++){
for (let j = 0; j < arr[i].length; j++){
retArr[i][j] = arr[j][arr.length - (i + 1)]
}
}
return retArr

let retArr = [[],[],[]]
for (let i = 0; i < arr.length; i++){
for (let j = 0; j < arr[i].length; j++){
retArr[i][j] = arr[arr.length - (j + 1)][i]
}
}
