You are given n segments on a number line; each endpoint of every segment has integer coordinates. Some segments can degenerate to points. Segments can intersect with each other, be nested in each other or even coincide. The intersection of a sequenc

题目描述: 找出一个序列中乘积最大的连续子序列(至少包含一个数). 样例: 比如, 序列 [2,3,-2,4] 中乘积最大的子序列为 [2,3] ,其乘积为6. 第一种解法,同最大和子序列的暴力求解法,直接求出每个子序列的乘积,取最大值. public class Solution { /** * @param nums: an array of integers * @return: an integer */ public int maxProduct(int[] nums) { int m
本篇博文给大家介绍前N个正整数的排列求解的三种方式.第一种是暴力求解法:第二种则另外声明了一个长度为N的数组,并且将已经排列过的数字保存其中:第三种方式则采用了另外一种思路,即首先获取N个整数的升序排列,然后对其位置进行随机交换以达到前N个整数的随机排列的目的.首先我们来看看第一种方式,具体代码如下: import java.util.Random; import org.junit.Test; public class App { private int n = 100000; @Test p
