Solution: Island Perimeter
Explore how to determine the perimeter of an island within a grid by analyzing land and water cells. Understand the algorithm that counts edges and removes shared boundaries between adjacent land cells. This lesson helps you apply matrix traversal and adjacency logic to solve perimeter problems 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. ...
