PP1 Week 3 Contest 2


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 = 2k for some integer k, then n is even. For example, 6 = 23 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.


Starts with the number of test cases n (1n20) 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 -10x10.


For each x, print either 'x is odd' or 'x is even' depending on whether x is odd or even.
