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].

Note: Try to come up as many solutions as you can, there are at least 3 different ways to solve this problem.

实现

void rotate(int nums[], int n, int k) {
    int temp;
    for (int step = 0; step < k; step++) {
        temp = nums[n-1];
        for (int i = n-1; i > 0; --i)
        {
            nums[i] = nums[i-1];
        }
        nums[0] = temp;
    }
}
