code:

#include<bits/stdc++.h>
#define NN 1500005
using namespace std;
const int N=1e9+7;
int a[N]={0,1},x[NN];
signed main(void)
{
	//freopen(".in","r",stdin);
	//freopen(".out","w",stdout);
	int n,o=1,maxx=0;
	scanf("%d",&n);
	for(int i=1;i<=n;i++)
	{
		scanf("%d",&x[i]);
		maxx=max(maxx,x[i]);
	}
	for(int i=2;i<=maxx;i+=o)
	{
		a[i]=1; 
		for(int j=1;j<=o;j++)
		{
			a[i+j]=0;
		}
		o++;
	}
	for(int i=1;i<=n;i++)
	{
		printf("%d",a[x[i]]);
		if (i<=n-1)
		{
			printf("\n");
		}
	}
	return 0;
}

是我c++没装对吗？

求助！！！
