#include<stdio.h>
int main()
{
    int i=1,n,x,a=0,b=0,c=0;
    scanf("%d",&n);
    while(i<=n)
        {
         scanf("%d",&x);
         if(x<0)
         a++;
         if(x=0)
         b++;
         if(x>0)
         c++;
         i++;
        }
         printf("%d %d %d",a,b,c);
}

if(x=0)   应该是 if(x==0)
