2 min read

It was the first contest of our birthday month, and we had to make it special. Not only did we double up the number of winners with special prizes for top women coders, but we had also had top tech companies such as CodeNation, Quadeye, Dialpad, and BetterPlace as our recruitment partners. It was a great contest with big prizes to bag, and it was as exciting as it gets. Well, we’ve got a recap of the entire thing ready. Enjoy!

A Problem-Set To Remember 

The Long Challenges always come packed with problems, and more often than not, a few of these are pretty tough. This time, Division One was given 10 problems to battle through during the duration of the 10-day. The most popular problem of the lot was Space Arrays. The problem got nearly 200 successful submissions alongside an accuracy rate of 59.5 percent. Players also seemed to enjoy problem Paparazzi Gennady as it saw more than 160 successful submissions. The tough problems for this Division included Random Walk Queries and Clique Boolean Expression. While Random Walk Queries got a total of only 29 correct answers, Clique Boolean Expression was even tougher as it gathered just 9 green ticks. 

For Division Two, the most solved problem was Interesting XOR! with more than 5.1k successful submissions. Problem Space Arrays was pretty popular here as well. The problem got a little over 5000 correct answers and had an accuracy rate of 30.78 percent. The villains of Division One made a reappearance here as they were once again the toughest problems to solve. Random Walk Queries saw a total of 12 successful submissions, whereas Random Clique Boolean had only 3 players getting the green tick. 

Meanwhile, Division Three was hard at work throughout the ten days. The problem that played crowd-favorite here was No Time To Wait as it saw 23,500+ successful submissions. Chef and Group was also a much-loved problem in this Division. The problem saw over 20k correct answers with an accuracy rate of 54.92 percent. Talking tough problems for the Division, we had Dense Graph and Locked Safe. While Dense Graph got to enjoy a total of 334 green ticks, Locked Safe was the players’ worst nightmare at only 45 correct answers. You can catch up with the video editorials for all the problems here – Video Editorials.
