HDU 1003 Max Sum

DP。

代码如下:

 1 #include<iostream>
 2 #include<cstring>
 3 #include<cstdio>
 4 
 5 using namespace std;
 6 
 7 int main()
 8 {
 9     int T, n, i, a, sum;
10     int k, t, x, y, maxn;
11     cin >> T;
12     for (k=1; k<=T; k++)
13     {
14         t=1;
15         sum=0;
16         maxn=-1000;
17         cin >> n;
18         for (i=1; i<=n; i++)
19         {
20             cin >> a;
21             sum+=a;
22             if (sum > maxn)
23             {
24                 maxn=sum;
25                 x=t;
26                 y=i;
27             }
28             if (sum < 0)
29             {
30                 sum=0;
31                 t=i+1;
32             }
33         }
34         printf("Case %d:\n", k);
35         printf("%d %d %d\n", maxn, x, y);
36         if (k != T)
37             cout << endl;
38     }
39     return 0;
40 }
