Seasonal coding challenges are competitive programming events that occur at specific times of the year, often organized by platforms like HackerRank, LeetCode, or Codeforces. These challenges typically last for a few weeks and invite participants to solve a series of algorithmic problems, ranging from easy to difficult. They provide an opportunity for coders to test their skills, learn new techniques, and compete against others globally. Participants can earn rankings, prizes, or recognition based on their performance. Seasonal coding challenges also foster a sense of community among programmers, encouraging collaboration and knowledge sharing. Many coders use these events to prepare for technical interviews or to improve their problem-solving abilities.
