我的代码：

#include<bits/stdc++.h>
#include<time.h>
#define int unsigned long long
#define double long double
const int N=2e6+5;
using namespace std;
int t;
signed main()
{
	cin>>t;
	for(int i=1;i<=t;i++)
	{
		int s;
		cin>>s;
		if(s<10)
		{
			cout<<"B\n";
			continue;
		}
		else if(s%10==0)
		{
			cout<<"E\n";
			continue;
		}
		else
		{
			cout<<"B\n";
			continue;
		}
	}
 	return 0;
}
