Even or Odd

A dance class at Riverbend Community Centre works in pairs. Before each session the tutor types in how many people signed up, and the screen has to say whether that many people split cleanly into pairs or whether someone will be left standing alone.

Task: Read the number of people and report whether it is even or odd.

Input

A single line holding one integer n, with 0 ≤ n ≤ 1,000,000.

Output

One line holding exactly Even or exactly Odd — capital first letter, no quotes, nothing else.

Example:

Input:
7

Output:
Odd
