Woburn Challenge 2017-18 Round 1 - Junior Division
"Ugh, It's been so hot out lately, why does it have to be ~32~
"~32~ degrees? That's freezing!"
You're had quite enough of confusing conversations with Americans who assume you're using Fahrenheit when Celsius is clearly the way to go. Rather than argue with them, you've settled for writing a program to conveniently convert temperatures measured in degrees Celsius to Fahrenheit instead.
You came across the following formula, which holds true given that ~F~ is a temperature in degrees Fahrenheit while ~C~ is that same temperature in degrees Celsius:
$$\displaystyle C = \frac 5 9 \times (F - 32)$$
Given a value of ~C~, which is an integer between ~-40~ and ~40~ (inclusive), determine the corresponding value of ~F~, so that you can express the equivalent temperature in degrees Fahrenheit for the Americans' benefit.
It's guaranteed that ~C~ will be chosen such that ~F~ will come out to exactly an integer, but you may output it with ~0~ or more digits after the decimal point.
The first and only line of input consists of a single integer, ~C~.
Output a single integer, the temperature in degrees Fahrenheit which is equivalent to ~C~ degrees Celsius.
