Sudoku is a logic-based number puzzle game, which consists of 81 cells which are divided into 9 rows, columns and 3x3 boxes. The goal is to place the numbers from 1 to 9 into the empty cells in such a way that in every row, column and 3x3 boxes each number appears only once. Analyse the grid to find the numbers that would fit into each cell.
