## 題目敘述

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.

:::success
某些數字是奇數，例如 $3$，因為它們不是 $2$ 的倍數。
某些數字是 $2$ 的倍數，它們不是奇數，是偶數。
更精確的來說，如果一個數字 $n$ 可找到一個整數 $k$ 使得 $n=2⋅k$ 成立，就說 $n$ 是偶數，
例如 $6=2⋅3$ 是偶數。

某些人搞不清楚數字是奇還是偶，一個常見的例子是去網路上搜尋以下問題
「$0$ 是奇數還是偶數？」
（別現在馬上去搜！你還沒解出這道問題呢！）

寫個程式幫助那些搞不清楚數字奇偶的人們。

## 輸入格式

Input begins with an integer $1\le n\le 20$ 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 $−10\le x\le 10$.

:::success
輸入第一行為一個整數 $1\le n\le 20$ 代表接下來有多少組的測試資料。
接下來 $n$ 行每行為一組測試資料，包含一整數 $−10\le x\le 10$。
:::

## 輸出格式

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

:::success
對每組 $x$ 依照 $x$ 是奇數還是偶數，輸出「$x$ is odd」或者「$x$ is even」。
:::

## Sample Input

3
10
9
-5

## Sample Output

10 is even
9 is odd
-5 is odd
