This is my code, why in 3 test cases doesn't work?

Answer 1

Hi I have solved this in python like this.
Cpp is really beautiful but it requires some time to debug, python is so boring.

import math
n = input()
t= int(input())
names=input().split(" ")
names.append(n)
names.sort()
inq = names.index(n)
print(math.ceil((inq+0.01)*1.0/t)*20)
