Leetcode 189. Rotate Array
题目
Input: [1, 2, 3, 4, 5, 6, 7] and k = 3
Output: [5, 6, 7, 1, 2, 3, 4]
Explanation:
rotate 1 step 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]Input: [-1,-100,3,99] and k = 2
Output: [3,99,-1,-100]
Explanation:
rotate 1 steps to the right: [99,-1,-100,3]
