给定一个数组,将数组中的元素向右移动 k 个位置,其中 k 是非负数。
示例 1:
输入:[1,2,3,4,5,6,7]
和 k = 3 输出:[5,6,7,1,2,3,4]
解释: 向右旋转 1 步:[7,1,2,3,4,5,6]
向右旋转 2 步:[6,7,1,2,3,4,5]
向右旋转 3 步:[5,6,7,1,2,3,4]
示例 2:
输入: [-1,-100,3,99]
和 k = 2
输出: [3,99,-1,-100]
解释:
向右旋转 1 步: [99,-1,-100,3]
向右旋转 2 步: [3,99,-1,-100]
说明:
class Solution: def rotate(self, nums, k): """ :type nums: List[int] :type k: int :rtype: void Do not return anything, modify nums in-place instead. """ if k == 0 or len(nums) < 2: return length = len(nums) n, i, j = 0, 0, 0 temp1 = nums[0] while n < length: j = (j + k) % length temp2 = nums[j] nums[j] = temp1 temp1 = temp2 if i == j: i = (i + 1) % length j = i temp1 = nums[i] n += 1
