Algorithm Contests are competitive events where participants solve complex problems using programming and mathematical skills. These contests often involve writing efficient algorithms to tackle challenges within a limited time frame. They are popular among students and professionals who enjoy problem-solving and coding. Many contests are organized by universities, tech companies, or online platforms like Codeforces and LeetCode. Participants can compete individually or in teams, and they are usually ranked based on the number of problems solved and the time taken. These contests help improve coding skills and foster a sense of community among programmers.
