给你一个整数数组nums,请你找出一个具有最大和的连续子数组(子数组最少包含一个元素),返回其最大和。 是数组中的一个连续部分。 示例1: 输入:nums = [-2,1,-3,4,-1,2,1,-5,4]输出:6解释:连续子数组 [4,-1,2,1] 的和最大,为 6 。
给你两个按非递减顺序排列的整数数组nums1和nums2,另有两个整数m和n,分别表示nums1和nums2中的元素数目。 请你合并nums2到nums1中,使合并后的数组同样按非递减顺序排列。 注意:最终,合并后数组不应由函数返回,而是存储在数组nums1中。为了应对这种情况,nums1的初始长度为m + n,其中前m个元素表示应合并的元...
输入:arr=[0,1,2,3,4,5,6,7,8]输出:[0,1,2,4,8,3,5,6,7]解释:[0]是唯一一个有0个1的数。[1,2,4,8]都有1个1。[3,5,6]有2个1。[7]有3个1。按照1的个数排序得到的结果数组为[0,1,2,4,8,3,5,6,7]示例2: 输入:arr=[1024,512,256,128,64,32,16,8,4,2,1]输出:[1...
【题目】Given an m x n matrix of non-negative integers representing the height of each unit cell in a continent, the “Pacific ocean” touches the left and top edges of the matrix and the “Atlantic ocean” touches the right and bottom edges. Water can only flow in four directions ...
题目难度:Easy 通过率:70.20% 相关话题 数学 https:///tag/math 相似题目 完美数 https:///problems/perfect-number/难度:简单 解题思路: 设计一个判断单个数是否是自除数的函数,比如取名为IsSelfDIv() IsSelfDIv函数的要点是: 排除数位中含有0的数
Can you solve this real interview question? Available Captures for Rook - You are given an 8 x 8 matrix representing a chessboard. There is exactly one white rook represented by 'R', some number of white bishops 'B', and some number of black pawns 'p'. E
https://leetcode.com/problems/island-perimeter/ 就是逐一遍历所有的cell,用分离的cell总的的边数减去重叠的边的数目即可。在查找重叠的边的数目的时候有一点小技巧,就是沿着其中两个方向就好,这种题目都有类似的规律,就是可以沿着上三角或者下三角形的方向来做。一刷一次ac,但是还没开始注意codestyle的问题,需要...
