给定一个数组(array),将数组向右旋转k步(k>=0)。 不需要输出,只改变原来的数组就可以。 Solution 1: 每次循环将数组的元素都向后移动一位,循环k次。 classSolution:defrotate(self, nums: List[int], k: int) ->None:foriinrange(k): previous= nums[-1]forjinrange(len(nums)): nums[j], previou...
func rotate(nums []int, k int) { n := len(nums) // 计算最后有多少数字会被移动到数组开始 k %= n // 翻转整个数组 reverse(nums, 0, n - 1) // 翻转前 k 个数字 reverse(nums, 0, k - 1) // 翻转后 n - k 个数字 reverse(nums, k, n - 1) } func reverse(nums []int, l...
Rotate an array of n elements to the right by k steps. For example, with n = 7 and k = 3, the array [1,2,3,4,5,6,7] is rotated to [5,6,7,1,2,3,4]. Note: Try to come up as many solutions as you can, there are at least 3 different ways to solve this problem. ...
LeetCode之Rotate Array 1、题目 Rotate an array of n elements to the right by k steps. For example, with n = 7 and k = 3, the array[1,2,3,4,5,6,7]is rotated to[5,6,7,1,2,3,4]. Note: Try to come up as many solutions as you can, there are at least 3 different ...
leetCode 33. Search in Rotated Sorted Array(c语言版本) bingo酱 I am a fighter 来自专栏 · leetcode每日斩 题目大意: 给定一个旋转升序的数组,所谓旋转就是假设把头和尾连接起来,然后找到最小那个数开始,往后开始就是升序的,直到再回到最小那个数为止。这样看起来就像一个环一样。 然后,现在给定一个数,...
