What could be the reason for getting a run time error for a program in python?

t=int(input())
c=[]
for i in range(t):
c=input()
a,b=int(input()).split()
print(a+b)
A simple program like this for finding the sum of two numbers is not getting executed. It shows ‘NZEC’ run time error. How do I fix it?
