LeetCode Problems' Solutions
A collection of C++ solutions to LeetCode coding problems, organized by problem number with links to both the original problems and solution code.
This repository is a large collection of solutions to coding problems from LeetCode, a platform used for practicing algorithm and data structure problems, often in preparation for software engineering interviews. The solutions are written primarily in C++, with some problems also having Java solutions.
The readme is almost entirely a table listing each problem by number and title, linking to both the original LeetCode problem and the corresponding solution file in the repository. Problems are tagged with their difficulty (Easy, Medium, or Hard) and cover a wide range of algorithm topics. The collection spans from early-numbered problems up through problem 1946, indicating it has been built up over time. There is no tutorial text or explanation of approaches — it is strictly a reference collection of working code solutions.
Where it fits
- Prepare for software engineering interviews by studying working solutions to common algorithm problems.
- Reference correct implementations when stuck on a LeetCode problem you're solving.
- Practice data structures and algorithms across a wide range of difficulty levels and topics.
