一维数组中求最大子数组的算法 package com.wangwang.mar; import java.util.Scanner; public class Sum { public static void main(String[] args) { // TODO Auto-generated method stub Scanner sc=new Scanner(System.in); System.out.println("输入数组长度"); int n=sc.nextInt()
perl中的引用和C中的指针一样,用"\"标识,引用后可使用符号"->"取值.解引用则在对应的数据类型前加$,@ 或%. 这里这里用两数组求和做示例,引用传递的子函数的用法. 1 use strict; 2 3 my @s1=(1,13,4,25,6,27,8,22); 4 my @s2=(11,2,34,5,6,23,1,54); 5 6 my @sum=sums(\@s1,\@s2); 7 8 foreach my $k(@sum){ 9 print &q
I 找一个连续最大子数组,sum加到nums[i], 如果前面子数组和<0则舍去,从头开始. class Solution { public: /** * @param nums: A list of integers * @return: A integer indicate the sum of max subarray */ int maxSubArray(vector<int> &nums) { // write your code here ; ;i<nums.s
Given an array nums and a target value k, find the maximum length of a subarray that sums to k. If there isn't one, return 0 instead. Example 1: Given nums = [1, -1, 5, -2, 3], k = 3, return 4. (because the subarray [1, -1, 5, -2] sums to 3 and is th
Given an integer array nums, find the contiguous subarray (containing at least one number) which has the largest sum and return its sum. Example: Input: [-2,1,-3,4,-1,2,1,-5,4], Output: 6 Explanation: [4,-1,2,1] has the largest sum = 6. Follow up: If
Find the contiguous subarray within an array (containing at least one number) which has the largest product. For example, given the array [2,3,-2,4],the contiguous subarray [2,3] has the largest product = 6. 这个求最大子数组乘积问题是由最大子数组之和问题演变而来,但是却比求最大子数组之和要复
