Summary
This episode demonstrates how to create a compile-time maze generator and solver using constexpr in C++14/17. Building on the constexpr random number generator from the previous episode, Jason shows how to implement complex algorithms like maze generation and pathfinding that execute entirely during compilation. The implementation includes constexpr-compatible data structures like a two-dimensional array for the maze and a stack for the depth-first search algorithm. The maze generator uses a depth-first search with backtracking to create the maze, while the solver uses a similar approach to find a path from the entrance to the exit. This example showcases the power of modern C++ constexpr capabilities for creating complex compile-time computations.
