# PWC219 - Sorted Squares

**TL;DR**

Here we are with TASK #1 from The Weekly Challenge #219. Enjoy!

# The challenge

You are given a list of numbers.

Write a script to square each number in the list and return the sorted list, increasing order.

Example 1`Input: @list = (-2, -1, 0, 3, 4) Output: (0, 1, 4, 9, 16)`

Example 2`Input: @list = (5, -4, -1, 3, 6) Output: (1, 9, 16, 25, 36)`

# The questions

Well, possibly Iâ€™d ask the range/domain of the input numbers, to figure out whether I have to get some big-numbers library for languages that need it.

# The solution

We will just follow the indications: square the numbers, sort them in increasing order, print them.

The Raku solutions allows us to show off:

```
#!/usr/bin/env raku
use v6;
sub MAIN (*@args) { @argsÂ».Â².sort.join(', ').put }
```

Yup, the `Â²`

really does square stuff!

The Perl alternative is good olâ€™ code that you can depend on:

```
#!/usr/bin/env perl
use v5.24;
say join ', ', sort { $a <=> $b } map { $_ * $_ } @ARGV;
```

â€˜nuff said, stay safe!
