Perl is one of the most popular text processing languages in the world. It allows you to create extremely efficient text parsers for all sorts of applications.

This interactive course will help you get up to speed on Perl, starting off with basic concepts like loops, strings, and arrays. You'll build your way up to more complex topics like data structures and packages.

No background knowledge is needed. Anyone willing to understand the principles and syntax of Perl to use it in the future will find this course useful.

## Problem statement 

Write a code which will check whether a given **integer** `$number` is **even** or **odd**. You're given a variable `$temp`. Set this to `0` if the `$number` is even and `1` if the `$number` is odd.

**Hint:** Think along the lines of using `if-else` condition.
### Input
An integer.
### Output
Boolean `0` if the number is even, and `1` if the number is odd.
### Sample input
```
number = 3
```

### Sample output

```
1
```

## Coding exercise
**Write your code below**. It is recommended that you try solving the exercise yourself before looking at the solution.

**Good Luck!**

#you are given a variable $number which has either an odd or even value

# Write your code here to find out if $number is even or odd 

$temp = -1; #set temp to 0 if $number is even
          #set temp to 1 if $number is odd
          


package Test;

sub square {

$number = @_[0];

$temp=-1; #set temp to 0 if number is even
#set temp to 1 if number is odd

if($number % 2 == 0){
  $temp = 0;
}
else{
  $temp = 1;
}
