You must write code that verifies the awarded points for a fictional sport are valid. This sport is a simplification of American Football scoring rules. This means that the score values must be any logical combination of the following four rewards:

• 6 points for a "touch-down"
• 3 points for a "field-goal"
• 1 point for an "extra-point"; can only be rewarded after a touch-down. Mutually-exclusive with "two-point conversion"
• 2 points for a "two-point conversion"; can only be rewarded after a touch-down. Mutually-exclusive with "extra-point"

A valid score could be 7, which can come from a single "touch-down" and then an "extra-point". Another example could be 6, from either a single "touch-down" or two "field-goals". 4 is not a valid score, since it cannot be formed by any well-combined rewards.

Input will consist of a single positive integer given on standard console input.

Print "Valid Score" or "Invalid Score" based on the respective validity of the given score.
