To boost problem-solving speed, focus on practicing problems under timed conditions. Familiarize yourself with algorithms and data structures, and improve your ability to recognize patterns in problems quickly.

Improving problem-solving speed requires a mix of knowledge, practice, and strategy. First, make sure you're comfortable with core algorithms and data structures like sorting algorithms, binary search, depth-first search (DFS), and breadth-first search (BFS). You should also know how to apply greedy algorithms and dynamic programming techniques. One of the most critical factors in coding competitions is your ability to recognize patterns in problems quickly. This skill can only be developed through regular practice with a wide range of problem types. Time management is crucial, so consider dividing your competition time strategically: spend the first few minutes understanding and categorizing problems by difficulty, and tackle the ones you are most familiar with first. After solving easier problems, you can spend more time on the harder ones. Another useful tip is to practice under real-time constraints by participating in mock contests or timed challenges on platforms like Codeforces, AtCoder, or LeetCode. Lastly, working on improving your typing speed and familiarity with your coding environment can save precious seconds during the contest.
