/**
 * Given: An array of strings where L indicates land and W indicates water,

 *
 * Challenge: Find and mark the ocean in the map by changing appropriate Ws to Os.
 * An ocean coordinate is defined to be the initial coordinate if a W, and
 * any coordinate directly adjacent to any other ocean coordinate.
 *
 * void findOcean(String map, int row, int column);

 * STDOUT:
 * WWWLLLW
