The “standard scratch” of a golf course is calculated by adding together the number of shots it should take to complete each hole. This score is then adjusted depending on the difficulty of the course.
For example:

2 holes take 5 shots (par 5) 2x5 = 10
10 holes take 4 shots (par 4) 10x4 = 40
6 holes take 3 shots (par 3) 6x3 = 18 10+40+18 = 68 shots in total
Difficulty adjustment -2 68-2 = 66
Standard Scratch = 66

Write a program that allows the user to enter the information required to calculate the standard scratch
score of a golf course. The standard scratch should then be calculated and displayed.

Input

How many par 3 holes are there?
