为啥用的哈希过不了?求大神解答!(代码附上)//别告诉我数组开小了?!
#include<iostream>
#include<stdio.h>
#include<string.h>
#define SIZE 10000000
using namespace std;
bool Hash[SIZE];
int main()
{
long long n;
while(cin>>n)
{
long long sol=0;
memset(Hash,0,sizeof(Hash));
while(n--)
{
long long a;
scanf("%lld",&a);
if(Hash[a])continue;
else Hash[a]=1;
sol++;
}
cout<<sol<<endl;
}
return 0;
}
