Machine Coding Round

This round involved solving a coding problem within a 30-minute time limit. Candidates were allowed to choose their preferred programming language. The problem statement was:

You are given an array arr of integers containing n elements and an integer k. Rotate the array to the right by k steps.

Example:

Input:

5
1 2 3 4 5
2

Output:

4 5 1 2 3

The provided solution involved calculating the effective rotation steps using the modulo operator (k % n), slicing the array, and concatenating the resulting segments.

function solution(n, arr, k) {
  const steps = k % n;
  const rotated = arr.slice(-steps).concat(arr.slice(0, n - steps));
  console.log(rotated.join(' '));
}
