Amusement Park

One of Tommy’s family members is planning a trip to an amusement park, and Tommy is interested in calculating the cost of a ticket based on the park's pricing guidelines. The amusement park offers different ticket rates for visitors of various ages and weights.

Here are the established guidelines for pricing:

• Children who are under $3$ years of age and individuals aged $70$ or older are granted free tickets.

• Children falling within the age range of $3$ to $12$ years qualify for a child's ticket priced at $\$10.$

• Teenagers and adults, aged $13$ to $64$ can acquire a regular ticket for $\$20.$

• Anyone within the age range of $65$ to $69$ is eligible for a senior ticket, which costs $\$15.$

• If a visitor is between $30$ and $40$ years old and has a weight more then$75$ kg, they are entitled to a discounted ticket priced at $\$18.$

Now, let's develop a program that takes as input the age and weight of the visitor and calculates the admission ticket price according to the amusement park's rules.

Input

The program expects the age in years $A$ and weight in kilograms $W$ of the visitor, both represented as integers on the first line.

• $1 ≤ A, W ≤ 200$

Output

If the admission ticket cost is $\$0$, the program will print "Free" in a single line. Otherwise, it will display the ticket price.
