April gets its name from the Latin word “aprit” meaning “to open.” The reference here is towards the opening of season, when the trees and flowers open. However, for the students with exams hovering over their head it is time “to open” their books for the final exams. Busy in preparing for their exams students look for a reason to break free from the everyday routine and dive into something exciting, something that will freshen up their minds, without asking too much from them. And we had just the perfect recipe for that in our April Challenge 2015. The ten day course of the contest allowed students to devour the delectable problem set of Andrii Mostovyi, Jakub Safin, Abhra Dasgupta, Lalit Kundu, Praveen Dhinwa, Vitalij Kozhukhivskij, Vasia Antoniuk, and Pavel Sheftelevich at their leisurely pace. With only 3 participants short of the 7K mark, you can say that they did enjoy the problem. And we will tell you more about it during the course of this (delayed) post. So, let’s start.
The problem set for the contest was tested by Sergey Kulik, who also was the part of our translation panel as Russian translator alongside our Mandarin translator, Gedi Zheng. While the problem setting panel ensured the appetizing problem set, the editorialist Surya Kiran, helped the problem related contest queries with the editorials. And our contest admin Praveen Dhinwa ensured a smooth run for the contest by his key inputs and helping hand when needed. The April Challenge 2015, started with nine problems, as the panel needed some more time to play with the tenth problem to make sure that it is contest ready. However, it wasn’t too long before the tenth problem was served.
While the panel was busy putting the final touches on the tenth problem, we found the participants having enjoying the problems so much that we have four out of the nine problems served initially cracked inside the first fifteen minutes of the contest. Problems BROKPHON, CHEFLCM, FRMQ, and DIVLAND received maximum love from the participants in the early stages, however, we all know which one got the maximum affection. The tenth problem PIANO1 made its appearance after an hour and half into the contest and within half an hour of its addition anta0 & kutengine cracked it in the gap of around 5 minutes. All this and we are still into the first days of the contest. As the day passed, the submissions started growing and the action in the rank tables started heating up.
As we moved into the later stages of the contest, the appearance of biggies like ACRush, kutengine, & scli hinted towards an exciting conclusion to the contest. The scenes on the Indian rank tables were a tad different. While, the names on there were not as celebrated as their global counterparts, we are sure all that will change soon after the after the April Challenge and we will get to see more of itisalways42, deathsurgeon, viv001, vijayarsenal10 and company. Now, to meet all those who made their mark on the rank tables, let us take you through the Indian and rest of the world rank tables.

The April Challenge 2015 might have had a brilliant start; however, it was not an altogether smooth ride. There were some missing test cases reported for problems DIVLAND and FRMQ, which were added upon identifying. Although, apart from those missing test cases, we had a rather fun filled contest. Now, before we part ways and move towards the April Cook-off 2015 blog post, let us take you through the editorials for April Challenge. We are sure you already would have gone through them, but if you have not check them below.
