A friend of mine, Jeff Goff (@DrForr) sadly killed in a scuba-diving accident while on vacation few days ago. I have known him for many years, mostly got to attend his talk at London Perl Workshop. I still remember his talk “The Art of Programming”. It was a very different experience where audience got to play with piece of paper during the entire talk. I only got the opportunity to have one-2-one conversation with him at The Perl Conference in Riga last year. I even had the pleasure to go to dinner with him one day during the conference. He was a gem of a person. He even contributed to CPAN. He would always encourage me, no matter what. Every time I post something on Twitter/Facebook, he would be the first to like or comment. He would always help me with Raku questions on Twitter.

May his soul rest in peace

COVID-19 seems to have taken the focus away from “The Weekly Challenge” last week. I have had few members sharing they couldn’t focus on weekly challenge because of COVID-19 pandemic. Even London has been affected badly. I hope things will get better soon. Please look after yourself and your family. Stay indoor and stay safe. For me, reading your contributions worked like a therapy. It helped me to forget about everything. Also doing the weekly challenge also helped me avoid watching news about the pandemic.

We are looking for volunteer to help us with Raku Reviews. So far, Laurent Rosenfeld and Ryan Thompson have done brilliant job with quality reviews.

TASK #1

Stepping Numbers

Write a script to accept two numbers between 100 and 999. It should then print all Stepping Numbers between them.

A number is called a stepping number if the adjacent digits have a difference of 1. For example, 456 is a stepping number but 129 is not.

TASK #2
