<div class="textblock"><p >Sudoku Solver using recursive implementation of brute-force algorithm. </p>
<p >Given an incomplete N*N Sudoku and asked to solve it using the following recursive algorithm:</p><ol type="1">
<li>Scan the Sudoku from left to right row-wise to search for an empty cell.</li>
<li>If there are no empty cells, print the Sudoku. Go to step 5.</li>
<li>In the empty cell, try putting numbers 1 to N while ensuring that no two numbers in a single row, column, or box are same. Go back to step 1.</li>
<li>Declare that the Sudoku is Invalid.</li>
<li>Exit.</li>
