About

  • A command-line tool for solving sudoku puzzles.
  • Install by running: cargo install sudoku-cli
  • If your input is a file path, sudoku-cli will read from the file. Otherwise it treats the string as input.
  • sudoku-cli reads the first 81 non-whitespace characters from the input and fills each row from left to right, starting with the top row.
  • sudoku-cli can output results to a file. The directory must already exist.
