    import re
for _ in range(int(input())):
    inp=input()
    isvalid="Invalid"
    if (re.fullmatch(r'[0-9a-zA-z]{10}',inp) 
    and len(set(inp))==10 
    and sum('0'<=c<='9' for c in inp)>2 
    and sum('A'<=c<='Z' for c in inp)>1):
            isvalid="Valid"
    print(isvalid)

    why not isdigit() or isalnum()? They allow unicode characters (decimal digits in other language locales) and superscripts. our goal for digits is to only have [0-9]
