Intro

This project implements a terminal version of the Sudoku game.

The full description of the project may be found here.

The game

According to the wikipedia:

Sudoku is a logic-based, combinatorial number-placement puzzle. The objective is to fill a 9×9 grid with digits so that each column, each row, and each of the nine 3×3 subgrids that compose the grid (also called "boxes", "blocks", or "regions") contain all of the digits from 1 to 9. The puzzle setter provides a partially completed grid, which for a well-posed puzzle has a single solution.

The Sudoku rules are:

1. Each row, column, and nonet can contain each number (typically 1 to 9) exactly once.
2. The sum of all numbers in any nonet, row, or column must be equal to 45.

Input
