Problem with ide

I am trying to solve the problem on page https://www.codechef.com/MARCH19B/problems/CHDIGER but even a code this :
a=input()
print(a)
t=int(a)
for i in range(0,a):
b,c=input().split(" ")
b=int(b)
c=int©
is giving an error Traceback (most recent call last):
File “prog.py”, line 1, in
a=input()
EOFError
