int arr[] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}; RotateArray ra = new RotateArray(); ra.leftRotate(arr, 8, 12); for (int i = 0; i < arr.length; i++) { System.out.print(arr[i] + " "); } } } Python 实现 def leftRotate(arr, k, n): k = k % ...
LeetCode之“数组”:Rotate Array 题目链接 题目要求: Rotate an array ofnelements to the right byksteps. For example, withn= 7 andk= 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 ...
图解:什么是旋转数组(Rotate Array)? 旋转数组 一文横扫数组基础知识 旋转数组分为左旋转和右旋转两类,力扣 189 题为右旋转的情况,今日分享的为左旋转。 给定一个数组,将数组中的元素向左旋转k个位置,其中k是非负数。 <p align='center'>图 0-1 数组 arr 左旋转 k=2 个位置</p>...
LeetCode笔记:189. Rotate Array 大意: 旋转一个有n个元素的数组,右移k步。 比如,n = 7,k = 3,数组 [1,2,3,4,5,6,7] 就被旋转为 [5,6,7,1,2,3,4]。 思路: 旋转本身没太多特别好说的,我的做法是用另一个数组来记录旋转后的内容,然后复制回原数组。当然记录时是从第nums.length-k个元素...
[leetcode] 33. Search in Rotated Sorted Array Description Suppose an array sorted in ascending order is rotated at some pivot unknown to you beforehand. (i.e., [0,1,2,4,5,6,7] might become [4,5,6,7,0,1,2]). You are given a target value to search. If found in the array...
如何使用Python解决Leetcode的Rotate Image问题? 题目: You are given an n x n 2D matrix representing an image. Rotate the image by 90 degrees (clockwise). Follow up: Could you do this in-place? 思路分析: 最笨的方法,重新开辟一个矩阵空间,做旋转。(题目要求最好能就地旋转) 更好的方法:先将矩...
Leetcode-48-Rotate-Image ou are given an n x n 2D matrix representing an image. Rotate the image by 90 degrees (clockwise). Note: You have to rotate the image in-place, which means you have to modify the input 2D matrix directly. DO NOT allocate another 2D matrix and do the ...
