HEADLINES


Welcome to the Week #200 of The Weekly Challenge.

Ryan Thompson, our in-house Perl and Raku reviewer came up with fun task to celebrate the 200th week of the weekly challenge. I am sure you will find it fun to work on it. I am looking forward to the interesting solutions and discussions around it.

Thanks to everyone who sent me kind messages, it means a lot.

I am trying my best to get back on track but still struggling. The best part is, I am not giving up for now. Wish me luck.

Today, we are giving away Coupon #23 to E. Choroba for the book, Learning Perl Exercises by brian d foy. I will share the details with you in a separate email.

Our solo sponsor Pete Sergeant has been a great support to keep us motivated. We are lucky that he agreed to continue the journey with us in the year 2022. I would like to personally thank Pete and his entire team for their generosity. It would be great if we could add few more to sponsor the prize money so that we could go back and declare weekly champions as we have done in the past. I hope and wish this will become possible in 2022. The amount doesn’t have to be huge. However, it would be nice to show off bunch of supporters. If an organisation comes forward and supports us then that would be the ultimate achievement.

Please find past solutions by respected guests. Please share your creative solutions in other languages.


Task 1: Arithmetic Slices

Submitted by: Mohammad S Anwar

You are given an array of integers.

Write a script to find out all Arithmetic Slices for the given array of integers.

An integer array is called arithmetic if it has at least 3 elements and the differences between any three consecutive elements are the same.


Example 1

Input: @array = (1,2,3,4)
Output: (1,2,3), (2,3,4), (1,2,3,4)

Example 2

Input: @array = (2)
Output: () as no slice found.

Task 2: Seven Segment 200

Submitted by: Ryan J Thompson

A seven segment display is an electronic component, usually used to display digits. The segments are labeled 'a' through 'g' as shown:


Seven Segment


The encoding of each digit can thus be represented compactly as a truth table:

my @truth = qw<abcdef bc abdeg abcdg bcfg acdfg acdefg abc abcdefg abcfg>;

For example, $truth[1] = ‘bc’. The digit 1 would have segments ‘b’ and ‘c’ enabled.

Write a program that accepts any decimal number and draws that number as a horizontal sequence of ASCII seven segment displays, similar to the following:


-------  -------  -------
      |  |     |  |     |
      |  |     |  |     |
-------
|        |     |  |     |
|        |     |  |     |
-------  -------  -------

To qualify as a seven segment display, each segment must be drawn (or not drawn) according to your @truth table.

The number "200" was of course chosen to celebrate our 200th week!



Last date to submit the solution 23:59 (UK Time) Sunday 22nd January 2023.
