点我看题目 题意 : 就是让你从一个数列中找连续的数字要求他们的和最大. 思路 : 往前加然后再判断一下就行. #include <iostream> #include<stdio.h> using namespace std; int main() { int n,start,end; cin>>n; int m ; ; k <= n ; k++) { cin>>m; ,sum = ,flag = ; ; i <= m- ; i++) { in…

HDU 1003    相关链接   HDU 1231题解 题目大意:给定序列个数n及n个数,求该序列的最大连续子序列的和,要求输出最大连续子序列的和以及子序列的首位位置 解题思路:经典DP,可以定义dp[i]表示以a[i]为结尾的子序列的和的最大值,因而最大连续子序列及为dp数组中的最大值.   状态转移方程:dp[1] = a[1]; //以a[1]为结尾的子序列只有a[1]:  i >= 2时, dp[i] = max( dp[i-1]+a[i],  a[i] ); dp[i-1]+a[i…
