Problem

There is a new conveyor belt sushi restaurant in town. Plates of sushi travel around the restaurant on a raised conveyor belt and customers choose what to eat by removing plates.

Each red plate of sushi costs $3, each green plate of sushi costs $4, and each blue plate of sushi costs $5.

Your job is to determine the cost of a meal, given the number of plates of each colour chosen by a customer.

Input

The first line of input contains a non-negative integer, R, representing the number of red plates chosen. The second line contains a non-negative integer, G, representing the number of green plates chosen. The third line contains a non-negative integer, B, representing the number of blue plates chosen.

Output

Output the non-negative integer, C, which is the cost of the meal in dollars.

Hint

This customer chose 0 red plates, 2 green plates, and 4 blue plates. Therefore, the cost of the meal in dollars is 0 × 3 + 2 × 4 + 4 × 5 = 28.
