C++编程求数组中重复的数字

题目:在一个长度为n的数组里的所有数字都在0到n-1的范围内. 数组中某些数字是重复的,但不知道有几个数字是重复的.也不知道每个数字重复几次.请找出数组中任意一个重复的数字. 例如,如果输入长度为7的数组{2,3,1,0,2,5,3},那么对应的输出是第一个重复的数字2. 思路:先将数组从小到大排列,然后一次比较相邻的两个数,若有重复,就将第一个重复的数字输出. 代码: // Parameters: // numbers: an array of integers // length: the…

Java:求字符串中邻接的数字为一个整体

public static void main(String[] args) { String strNumbers = "0123456789";//用来进行判断数字的 System.out.println("请输入一个字符串:"); String string = new Scanner(System.in).next(); //自定义输入 String[] strings = new String[string.length()];//自定义是字符串 Syst…

Maximal Rectangle, 求矩阵中最大矩形，参考上一题

问题描述: Given a 2D binary matrix filled with 0's and 1's, find the largest rectangle containing only 1's and return its area. For example, given the following matrix: 1 0 1 0 0 1 0 1 1 1 0 0 1 0 Return 6. 算法分析: 这道题可以应用之前解过的Largetst Rectangle in Histogr…

[LeetCode] Longest Line of Consecutive One in Matrix 矩阵中最长的连续1

Given a 01 matrix M, find the longest line of consecutive one in the matrix. The line could be horizontal, vertical, diagonal or anti-diagonal. Example: Input: [[0,1,1,0], [0,1,1,0], [0,0,0,1]] Output: 3 Hint: The number of elements in the given matr…

[LeetCode] Longest Increasing Path in a Matrix 矩阵中的最长递增路径

Given an integer matrix, find the length of the longest increasing path. From each cell, you can either move to four directions: left, right, up or down. You may NOT move diagonally or move outside of the boundary (i.e. wrap-around is not allowed). E…
