Number Guessing Game

The number guessing game is popular among elementary school students. Teachers encourage it to build their pupils' arithmetic skills and logical thinking.

To start the game, a friend thinks of a number in their head. Call this number $n_0$. The game then proceeds as follows.

1. Ask the friend to compute $n_1 = 3 \times n_0$, and to tell you whether $n_1$ is even or odd.
2. If $n_1$ is even, have them compute $n_2 = n_1 / 2$; if it is odd, $n_2 = (n_1 + 1) / 2$.
3. Have them compute $n_3 = 3 \times n_2$.
4. Ask the friend to compute the quotient $n_4 = n_3 / 9$ and tell you its value. (Here $n_4$ is the quotient of the division.)
5. Now you can recover the friend's original number: if $n_1$ was even, $n_0 = 2 \times n_4$; if it was odd, $n_0 = 2 \times n_4 + 1$.

For example, if the friend thought of $n_0 = 37$, then $n_1 = 111$, which is odd. Next $n_2 = 56$, $n_3 = 168$, and $n_4 = 18$. The friend tells you $n_4 = 18$. Since $2 \times n_4 + 1 = 37$, you can recover the number they first thought of.

Given $n_0$, write a program that determines whether $n_1$ is odd or even and computes $n_4$.

The input consists of several test cases. Each test case is a single line containing one integer $n_0$ ($0 < n_0 < 10^6$). The last line of the input contains a single $0$, which is not processed.

For each test case, print one line in the following format. First write the case number (starting from 1) followed by a period and a space, then write even if $n_1$ is even or odd if it is odd, then a single space, and finally $n_4$. For example, if the first case is odd with $n_4 = 18$, that line is 1. odd 18.
