就两个循环怎么还超时呢,测试数据都对啊~太郁闷了!!
#include <stdio.h>
int main()
{
int n,i,j,max,preMax,curMax,p,n1,n2;
int a[1000];
int l[1000];
int m[1000];
scanf("%d",&n);
while (n>0)
{
scanf("%d",&i);
for (j=0;j<i;j++)
{
scanf("%d",&a[j]);
}
curMax=0;
preMax=-2000000000;
p=0;
while (p<i)
{
curMax+=a[p];
if (curMax>preMax)
{
preMax=curMax;
}
if (curMax<0)
{
curMax=0;
}
l[p]=preMax;
p++;
}
max=m[1]=l[0]+l[1];
for (p=2;p<i;p++)
{
n1=m[p-1]+a[p];
n2=l[p-1]+a[p];
if (n1<n2)
n1=n2;
if (n1>max)
max=n1;
}
printf("%d\n",max);
n--;
}
return 0;
}
