1、关于leetcode 这是第一篇关于leetcode的题解,就先扯点关于leetcode的话。 其实很早前就在博客园看到过leetcode一些题解,总以为跟一般OJ大同小异,直到最近点开了一篇博文Leetcode 编程训练,无意间点进leetcode的主页看了下,乖乖,居然能用 ...
有序旋转数组是指将有序数组向左或者向右移动k个位置得到的结果,其查找算法不难理解,因为局部有序,因此很容易想到二分查找是最合适的方法,时间复杂度O(nlogn),本文总结四道相关的算法题目。 (一)旋转数组 题目:189. 旋转数组 题目描述: 给定一个数组,将数组中的元素向右 ...
《力扣算法训练提升》图解数组篇-打卡数组统计-【189】旋转数组 今日份打卡题[189. 旋转数组] 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。 具体描述 解题讨论 讨论归纳一:辅助数组,划分旋转区域 区域划分图 动画模拟 ...
壹 ❀ 引 今天来做一道同样简单,但是挺有趣的题,题目来自leetcode189. 旋转数组,题目描述如下: 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: 解释: 向右旋转 1 步: [7,1,2,3,4,5,6] 向右旋转 2 步 ...
in place交换 如果是k步,那么就是把后面k个放到前面了嘛。 我们先把整个数组reverse,然后把前面的reverse回来,再把后面的reverse回来 对于AB我们要通过reverse操作得到BA 那么先把AB reverse一次得到reverse(B)reverse ...
Given an array of integers A and let n to be its length. Assume Bk to be an array obtained by rotating the array A k positions clock-wise, we ...
描述 You 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 ...
