Solution: Island Perimeter
Explore how to determine the perimeter of an island represented in a grid matrix by applying a systematic algorithm. Learn to iterate through cells, identify land adjacency, and efficiently adjust perimeter calculations to solve this common matrix-based problem within interviews.
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. ...
