题目：1782.   The jackpot

思路：最大字段和

#include <cstdio>
#include <cstring>
#include <iostream>
#include <cmath>
#include <algorithm>
using namespace std;
#define maxn 10010
int dp[maxn],num[maxn];
int main()
{
    int n;
    while(scanf("%d",&n),n)
    {
        int mx=0;
        memset(dp,0,sizeof(dp));
        for(int i=1;i<=n;i++)
        {
            scanf("%d",&num[i]);
            if(num[i]>0)
                dp[i]=num[i]+dp[i-1];
            else
            {
                dp[i]=max(dp[i],dp[i-1]+num[i]);
            }
            mx=max(mx,dp[i]);
        }
        if(mx>0)
            printf("The maximum winning streak is %d.
",mx);
        else
            printf("Losing streak.
");
    }
}
