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
