Problem B

Some numbers are just, well, odd. For example, the number 3 is odd, because it is not a multiple of two. Numbers that are a multiple of two are not odd, they are even. More precisely, if a number $n$ can be expressed as $n = 2 * k$ for some integer $k$, then $n$ is even. For example, $6 = 2 * 3$ is even.

Some people get confused about whether numbers are odd or even. To see a common example, do an internet search for the query “is zero even or odd?” (Don’t search for this now! You have a problem to solve!)

Write a program to help these confused people.


Input begins with an integer $1 \leq n \leq 20$ on a line by itself, indicating the number of test cases that follow. Each of the following $n$ lines contain a test case consisting of a single integer $-10 \leq x \leq 10$.


For each $x$, print either ‘$x$ is odd’ or ‘$x$ is even’ depending on whether $x$ is odd or even.

Sample Input 1 Sample Output 1
10 is even
9 is odd
-5 is odd
