Question

Write a function count_islands(grid) that takes a 2D list representing a map of '1's (land) and '0's (water) and returns the number of distinct islands. An island is surrounded by water and is formed by connecting adjacent lands horizontally or vertically (not diagonally). Use recursion (DFS) for the solution.
