The February LunchTime concluded recently, and the contest was an absolute thriller. With some stunning problems in all the Divisions and participants who gave us quite the display of skills, it was an exciting 3 hours. 

The Amazing Platter Of Problems 

Even with its short duration, the LunchTime problem setters set some pretty tough problems for the players. This time was no different, and there was some major coding going on in the contest. Division One was given six problems to wade through, and the crowd favorite here was Average Sorting The problem got a total of 132 submissions, with an accuracy rate of 24.91%. Another popular problem among the top coders was Sed Mex, as the problem accumulated over a hundred submissions. Talking tough problems for the Division we had Minimum Divisibility Set and Hot Meals and Queues. The problems had all the coders perplexed as Minimum Divisibility Set got only 2 correct answers, while Hot Meals and Queues got a solo successful submission. 

Moving on to Division Two, the most solved problems were Coprime Range and Palpal Strings. Coprime Range got more than 2.3k green ticks, and Palpal Strings wasn’t far behind at 1900+ successful submissions. Sed Mex made an appearance in this Division as well, and it got nearly 300 correct answers. The toughest problems in this Division were Independent Set and Chef and Reordering. Independent Set got a total of 29 submissions, with an accuracy rate of 9.51 percent. Chef and Reordering was even more elusive as only 3 players were able to solve the problem. 

Meanwhile, Division Three was busy with their own lot of problems. Smallest Possible Whole Number was the unrivaled favorite here, as it brought in nearly 5,500 successful submissions. Daanish and Problems was another popular question, as it saw 4,800+ correct answers and an accuracy rate of 74.92%. On the opposite end of the spectrum, problems See Max and Independent Set were the villians of the Division. While Sed Max saw a total of nearly 50 green ticks, only 4 players were able to solve Independent Set.
