C++ Sudoku Solver

Summary

This is a Sudoku Solver Xcode project built using C++ with simple backtracking algorithm.

To run and test the solver:

• Clone the repository
• Open the project using Xcode
• The underlying sudoku puzzle is a 2D vector, vector<vector<int>> vi where it contains 0 - 9, as its cell elements, 0 being an unfilled cell.
• To test this code with other puzzle, simply modify the 2D vector in main.cpp. and then run the project.

Concepts Learned

• C++ Templates
  • template<class Puzzle> and template<typename T>
• C++ header files (.hpp)
• Exception handling
  • std::exception
  • try, throw, catch
  • Custom exception
• struct
• namespace and the scope operator ::
• assert command
• Smart Pointer
  • std::unique_ptr<T> and std::make_unique<T>()
