Solution: Island Perimeter
Understand how to calculate an island's perimeter on a grid by traversing each cell, checking adjacency, and adjusting counts for shared edges. Explore the algorithm's logic that simplifies the problem to constant space complexity and linear time complexity, enabling you to solve similar matrix-based coding challenges effectively.
We'll cover the following...
Statement
You are given a grid with dimensions row x col, where each cell represents either land (grid[i][j] = 1) or water (grid[i][j] = 0). The grid satisfies the following conditions:
Cells are connected only horizontally or vertically (not diagonally).
The grid is surrounded by water and contains exactly one island, consisting of one or more connected land cells.
The island has no lakes, meaning no water is enclosed within the island that connects to the surrounding water. ...
