References and summary for leetcode high-frequency algorithm problems

Data Structure and Algorithms Based on LeetCode

Solutions and practices for data structure and algorithms (DSA), refering to the high frequency questions in LeetCode.

All the solutions are located in the \src dir. It only supports C++/C++11 now.

The solution for every question has run pass the tests online and explains the detailed methods with its complexity in the \doc and every source code in \src.

Built With

This project is built with following tools:

• C++ version: C++11
• Build system: CMake
• C++ compiler: g++
• Libraries: STL only
• Code coverage: lcov (note: it should show the code coverage is below 100%)
• CodeCov (code coverage is measured by CodeCov).
• Source & Tests: \src

Prerequisites

To build the project you need to install CMake. Here are the instructions. To create code coverage report you need to install lcov. Download lcov from here you can download latest lcov and here are instructions. This reports will be later uploaded to CodeCov servers.
