Number guessing is a popular game between elementary-school kids. Teachers encourage pupils to play the game as it enhances their arithmetic skills, logical thinking, and following-up simple procedures. We think that, most probably, you too will master in few minutes. Here’s one example of how you too can play this game: Ask a friend to think of a number, let’s call it n0. Then:
Your program will be tested on one or more test cases. Each test case is made of a single positive number (0 < n0 < 1,000,000).
The last line of the input file has a single zero (which is not part of the test cases.)
For each test case, print the following line:
k. B Q
Where k is the test case number (starting at one,) B is either ’even’ or ’odd’ (without the quotes) depending on your friend’s answer in step 1. Q is your friend’s answer to step 4.
37 38 0
1. odd 18 2. even 19
