Instead only set the cloned array's cells in the body of this method. And then at the <em>end</em> of the method either iterate through the cloned board copying it's results into the original board or else return the cloned board and when calling the method use it to set its results into the board... i.e.,</p> <pre><code>board = updateMatrix(board, birthLive); </code></pre>
