Rotate Array

[LeetCode] Rotate Array

void rotate(vector& nums, int k) { deque dq; for (int j = 0; j < nums.size(); j++) dq.push_back(nums[j]); nums.clear(); for (int i = 0; i < k; i++) { int val = dq.back(); dq.pop_back(); dq.push_front(val); } while (!dq.empty()) { nums.push_back(dq.front()); dq.pop_front(); } }
