Valid/Invalid

s=input()
cnt=0
if s[0].isalpha():
    cnt=cnt+1
if len(s)>=8:
    cnt=cnt+1
for ltr in s:
    if ltr.isdigit():
        cnt=cnt+1
        break
for ltr in s:
    if not ltr.isdigit() and not ltr.isalpha():
        cnt=cnt+1
        break
if cnt==4:
    print("Valid")
else:
    print("Invalid")
