Even or Odd

Given an integer, determine whether it is even or odd.

Input

A single line containing an integer n (can be negative) with at most 19 digits, not counting the minus sign.

Output

Print Even if the number is even, or Odd if the number is odd.

Examples

Input:  4
Output: Even

Input:  7
Output: Odd

Input:  0
Output: Even

Input:  -3
Output: Odd

Negative numbers work the same way: -3 % 2 is -1 in most languages, but in Python it's 1. Either way, it's not 0, so -3 is odd.
