Q: LeetCode 189. Rotate Array
I have a working solution for this problem that was accepted in LeetCode:
"Given an array, rotate the array to the right by k steps, where k is non-negative."
function rotate(nums, k) {
for (let i = 1; i <= k; i += 1) {
const poppedNum = nums.pop();
nums.unshift(poppedNum);
}
return nums;
}
// rotate([1, 2, 3, 4, 5, 6, 7], 3) -> [5, 6, 7, 1, 2, 3, 4]
Questions:
Would the time complexity be O(k) and space complexity be O(1)?
Is there a better way to solve this? The question asked to rotate the elements in-place if possible, but I am not sure how to accomplish this at the moment.
