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.
