Sudoku Solver and Generator
Implement a Sudoku solver and puzzle generator from scratch in modern C++ with zero external dependencies. You solve any valid board with backtracking, then generate fresh puzzles with a unique solution by removing clues carefully. A classic algorithms project centred on recursion and constraint checking.

What You'll Build
A command-line program that solves a given 9x9 Sudoku via backtracking and generates new puzzles at chosen difficulty levels, each guaranteed to have exactly one solution.
Learning Objectives
- Represent the grid with a std::array of 81 cells
- Validate rows, columns, and boxes with constraint checks
- Solve the board with a recursive backtracking search
- Count solutions to confirm a puzzle is uniquely solvable
- Generate a full board by randomised filling with the <random> library
- Remove clues while preserving a single solution
- Separate solver, generator, and board display into functions
