Please tell me what is wrong in my code:

try:
       def mod_power_func(x,n,m):
           if n==0:
               return 1
           elif n%2==0:
               return(mod_power_func((x*x)%m,int(n/2),m))
           else:
               return(x*mod_power_func((x*x)%m,int(n-1)/2,m))    
       def main():
           t=int(input())
           for _ in range(t):
               k=int(input())
               falg=1
               s=[int(x) for x in input().split()]
               sum=0
               for i in range(1,len(s)):
                   if s[i-1]&s[i] != s[i-1]:
                       falg=0    
                       break
                   else:
                       sum+=(bin(s[i-1]&s[i]).count("1"))
               if falg!=0:
                   print(mod_power_func(2,sum,1000000007))    
               else:
                   print(0)
       if __name__ == "__main__":
           main()
   except:
       pass

I don’t see you inputting n. Even if you don’t use it, you still need to input it.

My bad i forgot it , but it is still showing an error :frowning:

Your power function is probably wrong. I changed it to the inbuilt pow and it worked.

Thank you sir.
