Counting Islands: DFS and BFS Approaches for Grid Traversal Problems
Problem 1: Island Counting
Approach Overview
To solve the island counting problem, we need to traverse a 2D grid where 1s represent land and 0s represent water. An island consists of all connected land cells horizontally or vertically. We'll explore two traversal strategies: Depth-First Search (DFS) and Breadth-First Search (BFS).
