NZEC error each time i try submitting the code

So this is my first time using codechef. and I’m trying the NUMCOMP exercise.
I keep on getting the NZEC error for this code…
When i use the custom inputs, it works perfectly fine.
can someone help me understand what I’m not getting right?

T=int(input())
x=0
while(x<T):
a, b, n=input().split(" ")
a=int(a)
b=int(b)
n=int(n)
if (pow(a,n)>pow(b,n)):
print(“1”)
elif(pow(a,n)<pow(b,n)):
print(“2”)
elif(pow(a,n)==pow(b,n)):
print(“0”)
x=x+1
