WebNov 3, 2024 · 3 3. Use a proper data structure for your grid or at least add an abstraction so you can quickly access a given (i,j) pair. For a recursive algorithm you have to pass in the distance so far as an extra parameter (eg waveAlgorithm (int** arr, int i, int j, int distance) ). You should then only proceed if the given (i,j) pair is in bounds of your ... http://www.roborealm.com/help/Grassfire.php
