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]forjinra
解决:可以计算a1位置移动后的下一个位置a2 = (a1 + k) % n,然后让nums[a2] = nums[a1],依次类推,直到下一个位置an回到起点位置 也就是 a,这样循环下去,总会将所有元素替换掉吧。 3.我试着编写出一个循环程序,提交后发现程序存在严重漏洞,如果 n % k = 0 或者 k % n = 0,我们执行这个程序会发...
Can you solve this real interview question? Rotate Array - 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
class Solution: def rotate(self, nums: List[int], k: int) -> None: """ Do not return anything, modify nums in-place instead. """ n: int = 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 Solution.reverse(nums, 0, n - 1) # 翻转前 k 个数字 Soluti...
