Contestants Reactions Each year we ask for feedback from the competitors. Here's a sampling of what we received... Thank you, Dyalog, for this experience. This is my second year in the contest and after taking an elementary course The Dyalog APL competition is a strong incentive for people to invest time and energy to learn and practice this powerful I enjoyed the competition a lot, and I intend to investment than I though it was going to be at dynamically. ... I am looking forward to been so easy to get a basic understanding of APL, and at the same time it has been a huge challenge to begin thinking in arrays. guys, I've had a lot of fun! Recreation and Games Problem 2. It has been an excursion into history for me - "just getting the job done". I thoroughly enjoyed the This competition was a fun opportunity to learn a unique programming language. computational language. It was very interesting, informative and fun. Thanks for the help and quick responses to emails. participate again once I start my PhD. first, but that was largely my own fault. attending next competition about APL. Thank you so much for this competition. finding out eg. about the IBM 360 etc. competition this time around because it was algorithmically challenging and required thinking outside of the box. It also made learning more and more of the symbols fun. APL has been very different from everything I've The problems appeared very interesting to me, and in data structures and algorithms and a dedicated upper- It was a fun competition, a little more time I really like APL. It makes me think I have really enjoyed this competition. It has surprised me that it has The competition is great. You've done a I enjoyed this contest. the variety of the problems. Great ! And this time not only for students I really enjoyed the competition, especially known (except maybe for Lisp). I really liked the contest! level course, I think I've come a long way in understanding I picked up a few more APL tricks! great job collecting those tasks. Thanks I attempted all the problems except for I really enjoyed the way APL works with operators that there is a choice in making things work, rather than For me, it was an opportunity to challenge myself to get back I didn't find anything that needs improving which seems a bit like quantum mechanics! Some of the problems were quite challenging to write elegant solutions to... to practice and dive deep in the new features brought by Dyalog APL. I was pleased to find an incredible and complete APL platform.

I am from China and majoring in Computer Science. I can handle python, java and c++ and APL. By the way, I learnt APL 10 days ago by myself when I got the email about the competition.
