The Weekly Challenge

09. TASK #1: First Unique Character

HEADLINES

Welcome to Week #180 of the weekly challenge.

Today, we are giving away Token #3 to Robert DiCicco for the book, Learning Perl Exercises by brian d foy. I will share the details with you in a separate email.

Second consecutive week, I took break from weekly challenge. The end result, I am dropped to rank #16 in the leader board. Luckily less competition in Guest Leader Board, I am still holding my rank #15. Hopefully next week, I will try to participate. It has been the most busiest week for me.

Full credit goes to Laurent Rosenfeld, for holding the rank #1 for the longest period. I don’t see imminent threat to his position. As far as Guest Leader Board is concerned, Abigail is by far way ahead of everyone. Although he has taken break for the time being, still his position is quite safe.

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.
