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 backgrounds, including students and professionals. Many coding competitions are organized by platforms like Codeforces, LeetCode, and HackerRank. They can vary in format, ranging from timed contests to longer challenges that span several days. Participants often work individually or in teams, and winners may receive prizes, recognition, or opportunities for internships and jobs in the tech industry.
