FooBar Announcements

Hi everyone! We want to share with you a nice set of CP problems hand-picked by Priyansh who is an alumni from our college and an ICPC World Finalist. It is called the CP-31 sheet. This sheet contains 31 problems in each rating from 800 to 1600. Every single problem contains a very interesting idea that can be reused in a lot of problems. If you're a CP beginner, we highly recommend trying it out. This should also be a good practice for our upcoming Div2 Prosorts. Link: https://www.tle-eliminators.com/cp-sheet

ProSort [109] Valentine's Special Date: 16th February 2024 (Friday) Time: 4:00 PM Venue: TBA Continuing with what has become a FooBar tradition, we are organizing a Valentine's Special ProSort on 16th Feb (Friday). Romantic or not, with the ambience of chocolates, heart-shaped balloons, and a weird enjoyable problem set, this ProSort will be a unique experience everyone must have. On top of that, winners will receive prizes. Don't have a date? That's alright! Just invite a friend or acquaintance to the ProSort. After all... It's not a Date. It's a ProSort! Team Format: Teams of 2 (Can be just friends) The contest will be based on the idea of the April Fool's Contest on Codeforces. This will be a joke competition in which solving the problem may be easier than figuring out what the actual task is. Sounds exciting?
