为什么会WA,我的思路很清晰呀?(我还发现,好象数据一长就读不进去了)#include <iostream.h>
#include <stdio.h>
#include <stdlib.h>
long a[10000];
long n,k;
void work(int i,long sum)
{
if (i>n){
if (sum %k==0) {
printf("Divisible\n");
exit(0);
}
}
else {
work(i+1,sum+a[i]);
work(i+1,sum-a[i]);
}
}
int main()
{
cin>>n>>k;
memset(a,0,sizeof(a));
int i;
for (i=1;i<=n;i++) cin>>a[i];
work(2,a[1]);
printf("Not divisible\n");
return 0;
}
