You have to find the number of distinct islands where a group of connected 1s (horizontally or vertically) forms an island. Two islands are considered to be distinct if and only if one island is not equal to another (not rotated or reflected). Example 1: Input: grid[][] = {{1, 1, 0, 0, 0}, {1, 1, 0, 0, 0}, {0, 0, 0, 1, 1},
Sep 30, 2016 · Solution 1: Union-Find. We use a two-dimensional array grid g r i d to represent a map, where 0 0 and 1 1 represent water and land respectively. Initially, all cells in grid g r i d are water cells (i.e., all cells are 0 0), and we use a variable cnt c n t to record the number of islands.
