Rotate Array

Rotate an array of n elements to the right by k steps.

For example, with n = 7 and k = 3, the array [1,2,3,4,5,6,7] is rotated to [5,6,7,1,2,3,4].

public class Solution {
    public void rotate(int[] nums, int k) {
        if(nums.length == 0 || k % nums.length == 0 || nums.length == 1)
            return;
        int nums_copy[] = new int[nums.length];
        k = k % nums.length;
        k = nums.length - k;
        for(int i = 0; i < nums.length; i++){
            if(k >= nums.length) 
                k = 0;
            nums_copy[i] = nums[k++];
        }
        
        for(int i = 0; i < nums.length; i++)
            nums[i] = nums_copy[i];
    }
}
