import re
for _ in range(int(input())):
    uid = input()
    uid = "".join(sorted(uid))
    if ("[A-Z]{2}",uid) and #2 uppercase alphabets"\d{3}",uid) and #3+ digits
        not"[^A-Za-z0-9]",uid) and #no nonalphanumeric
        not"(\w)\1",uid) and #no repetition
        len(uid) == 10): #10 characters long
