Problem with STRHH

I’ve got wrong answer but my code is working good i tested it on 20 diffrent words and it works but website still says the code is not working.

a = int(input())
i = 0
while i < a:
    b = input()
    c = len(b)
    d = c / 2
    e = ""
    j = 0
    while j < d:
        e = e + b[j]
        j = j + 2
    print(e)
    i = i + 1
