I am stuck with a runtime error in UVA Online Judge problem 11559, Event Planning

for _ in range(int(input())):
    lst = list(map(int, input().split()))
    if len(lst) == 1: print(0)
    else: print(max(lst[1:]))

I have run it on my local PC, but it doesn't have error message. I have also added a code for checking if it N is 0 .

How can I solve the error? Is it possible to see the error text?
