# Program for n-th even number

Given a number n, print the nth even number. The 1st even number is 2, 2nd is 4 and so on.

**Examples:**

Input : 3 Output : 6 First three even numbers are 2, 4, 6, .. Input : 5 Output : 10 First five even numbers are 2, 4, 6, 8, 19..

The nth even number is given by the formula 2*n.
