Given an array, rotate the array to the right by k steps, where k is non-negative. Example 1: Input: [1,2,3,4,5,6,7] and 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…

将包含 n 个元素的数组向右旋转 k 步.例如,如果  n = 7 ,  k = 3,给定数组  [1,2,3,4,5,6,7]  ,向右旋转后的结果为 [5,6,7,1,2,3,4].注意:尽可能找到更多的解决方案,这里最少有三种不同的方法解决这个问题. 详见:https://leetcode.com/problems/rotate-array/description/ Java实现: 方法一: class Solution { public void rotate(int[] nums, i…

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 pro…

Given an array, rotate the array to the right by k steps, where k is non-negative. 给定一个数组,并且给定一个非负数的值k, 把数组往右旋转k步,要求不返回新的数组,直接改变原数组 例子1: 给定数组: [1,2,3,4,5,6,7] 给定 k = 3 输出数组: [5,6,7,1,2,3,4] 解析: 往右旋转1步: [7,1,2,3,4,5,6] 往右旋转2步: [6,7,1,2,3,4,5] 往右旋转3步:…

class Solution {public: void rotate(vector<int>& nums, int k) { int n=nums.size(); int i=0; //------------------- //解法一  会超时 //-------------------- k=k%n; while(i<k){ int temp=nums[n-1]; for(int j=n-1;j>0;j--){ nums[j]=nums[j-1]; } nums[0]…

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 pr…
