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].
class Solution {
public:
void rotate(
vector<int>& nums,
int k) {
vector<int> t = nums;
for (
int i =
0; i < nums.size(); ++i) {
nums[(i + k) % nums.size()] = t[i];
}
}
};
