Prepare for your coding interview with practical tips that will help you study more effectively. Read what to focus on before solving LeetCode problems, how to recognize what you need to do and why, organize your preparation, and avoid common mistakes during the coding interview preparation process.
Read moreIn this post I compare Fast & Slow Pointers, Two Pointers, and Sliding Window patterns: how each pattern works, how pointers move, their key differences, and how to recognize which approach to use in LeetCode problems and coding interviews.
Read moreThe Prefix Sum pattern is one of the most useful array techniques for solving LeetCode problems involving subarray sums, range queries, cumulative values, and counting subarrays. This section covers common variations, recognition rules, and practical examples from LeetCode.
