Coding competitions are events where programmers and computer enthusiasts compete to solve problems using code. Participants are typically given a set of challenges that test their algorithmic skills, problem-solving abilities, and coding efficiency. These competitions can be held online or in-person and often attract individuals from various skill levels, from beginners to experts. Many coding competitions are organized by platforms like Codeforces, LeetCode, and HackerRank. They may offer prizes, recognition, or opportunities for job placements. Competitors often work under time constraints, which adds an extra layer of challenge and excitement to the experience.
