Probability One

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 it in a 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:

1. Ask your friend to compute n₁ = 3n₀ and to tell you if n₁ is even or odd.
2. If n₁ is even, ask your friend to compute n₂ = n₁ / 2. If, otherwise, n₁ was odd, then let your friend compute n₂ = (n₁ + 1) / 2.
3. Now ask your friend to calculate n₃ = 3n₂.
4. Ask your friend to tell you the result of n₄ = n₃ / 9. (n₄ is the quotient of the division operation. In computer lingo, “/” is the integer division operator.)
5. Now you can simply reveal the original number by calculating n₀ = 2n₄ if n₁ was even, or n₀ = 2n₄ + 1 otherwise.

Here's an example that you can follow: If n₀ = 37, then n₁ = 111 which is odd. Now we can calculate n₂ = 56, n₃ = 168, and n₄ = 18, which is what your friend will tell you. Doing the calculation 2n₄ + 1 = 37 reveals n₀.

Input Specification

Your program will be tested on one or more test cases. Each test case is made up 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.)

Output Specification

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, and Q is your friend's answer to step 4.
