那位大侠帮我看看这段程序有什么错!老是WA#include <stdio.h> #include <stdlib.h> long b[50000]={0}; long c[50000]={0}; int a[50000]={0}; int MaxSum(int m,int n) { int i,j; long max,sum=-500000000; if(n<m||m<1)return 0; for(i=1;i<=m;i++) { b[i]=b[i-1]+a[i]; c[i-1]=b[i]; max =b[i]; for(j=i+1;j<=i+n-m;j++) { b[j]=b[j-1]>c[j-1]?b[j-1]+a[j]:c[j-1]+a[j]; c[j-1]=max; if(max<b[j])max=b[j]; } c[i+n-m]=max; } for(j=m;j<=n;j++) if(sum<b[j])sum=b[j]; return sum; } int main(int argc, char *argv[]) { int i,j,k; int n,m; long sum[30]={0}; scanf("%d",&n); for(i=0;i<n;i++) { scanf("%d",&m); for(j=1;j<=m;j++) scanf("%d",&a[j]); printf("\n"); sum[i]=MaxSum(2,m); } for(i=0;i<n;i++) printf("%ld\n",sum[i]); system("PAUSE"); return 0; } Followed by:
