The Weekly Challenge

09. TASK #1: Consecutive Arrays

HEADLINES

Let’s welcome Week #131 with 3 new members i.e. Rich Snyder, Ivan Dimitrov and Conor Hoekstra.

We now have 240 members and 10 guests.

Conor Hoeksta introduced new language J to Team PWC.

After relatively quiet Week #129, last week was much better.

Thanks for 38 Perl, 19 Raku and 13 blogs contributions. Above all we had 26 guest contributions in 17 languages.

Week #130 was special for me as I made a comeback after a gap of 7 weeks with solution to Odd Number task in Perl.

If you have any suggestions to make the weekly challenge more interesting and fun then please do share with us.

Last but not least, I would like to thank each and every member for their support and encouragement.

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 2021. 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 2021. 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.
