Given an integer array nums
, rotate the array to the right by k
steps, where k
is non-negative.
Example 1:
- Input: nums = [1,2,3,4,5,6,7], k = 3
- Output: [5,6,7,1,2,3,4]
Explanation:
- rotate 1 steps to the right: [7,1,2,3,4,5,6]
- rotate 2 steps to the right: [6,7,1,2,3,4,5]
- rotate 3 steps to the right: [5,6,7,1,2,3,4]
Example 2:
- Input: nums = [-1,-100,3,99], k = 2
- Output: [3,99,-1,-100]
Explanation:
- rotate 1 steps to the right: [99,-1,-100,3]
- rotate 2 steps to the right: [3,99,-1,-100]
Constraints:
- 1 <= nums.length <= 105
- -231 <= nums[i] <= 231 - 1
- 0 <= k <= 105
