#include
using namespace std;
int main()
{
bool flag=false;
int N,i,t=0;
cin>>t;
while(t–)
{
cin>>N;
int a[N];
for(i=0;i<N;i++)
{
cin>>a[i];
}
for(i=0;i<N/2;i++)
{
if(a[i]-a[i+1] < 1 && a[N/2]==7 && a[i]==a[N-i-1])
{
flag=true;
}
else
{
flag=false;
break;
}
}
if(flag)
cout<<“yes”;
else
cout<<“no”;
}
return 0;
}

Make sure that your code compiles before you ask questions. Otherwise you will not get any answers.

You are not checking that the numbers in rainbow array are in range of [1,7] only. You ought to search forums for previous such questions, it is a very common error done by people.
