Here you can find efficient solutions to LeetCode problems using modern readable and self-explained code. C++ is a main programming language used to solve the problems. Sometimes STL algorithms and/or data structures are not used for easy level problems for educational purposes. PostgreSQL dialect is used to solve database-related problems. Bash is used to solve shell-related problems. All solutions have optimal runtime complexity and most of them beats 100% mark, based on runtime performance.
At each solution file could be found:- time complexity analysis
- space comlexity analysis
- runtime performance copmared to other solutions using the same language
- link to a leetCode solution's submission
- link to a leetCode solution's post
