rotate(ar[], d, n) that rotates arr[] of size n by d elements python code example

Example 1: python left rotation

def rotate(l, n):
    return l[n:] + l[:n]

print(rotate([1, 2, 3, 4, 5], 2))

#output : [3, 4, 5, 1, 2]

Example 2: rorate array

function rotateArray(A, K) {
    if (!A.length) return A;
    let index = -1;
    while (++index < K) {
        A.unshift(A.pop());
    }
    return A;
}

[
    rotateArray([3, 8, 9, 7, 6], 3),
    rotateArray([0, 0, 0], 1),
    rotateArray([1, 2, 3, 4], 4),
    rotateArray([], 4),
].join(' | ');
