#include<bits/stdc++.h>
using namespace std;
int main()
{
int t;
cin>>t;
while(t--)
{
int n;
cin>>n;
int a[n];
int t=0;
for(int i=0;i<n;i++)
{
cin>>a[i];
if(a[i]==1) t++;
}
if(n<10||n>13)
{
cout<<"No"<<endl;
continue;
}
sort(a,a+n);
if(a[0]!=1)
{
cout<<"No"<<endl;
continue;
}
if(t<2)
{
cout<<"No"<<endl;
continue;
}
int max1=a[n-1];
int f=0;
for(int i=0;i<n-1;i++)
{
t=a[i+1]-a[i];
if(t>2&&a[i+1]!=max1)
f=1;
}
if(f) cout<<"No"<<endl;
else
cout<<"Yes"<<endl;
}
return 0;
}
这程序好像有点Bug，我给组数据试试？
