The ACM International Collegiate Programming Contest is a big competition where lots of smart people (college students) get together and try to solve problems using computer programming. It's kind of like a giant puzzle-solving contest.
During the contest, teams are given problems to solve and they have to write computer programs to solve them. The problems can be really tricky and require a lot of thinking and problem-solving skills.
The goal of the competition is to see which team can solve the most problems in the shortest amount of time. The teams are scored based on how many problems they solved correctly and how long it took them to solve them.
The competition is held all around the world and attracts some of the best and brightest college students. It's a great way for students to show off their programming skills and compete against their peers.
