Solution: Island Perimeter
Explore how to calculate the perimeter of a single island within a grid by iterating through the matrix and adjusting for shared edges between connected land cells. Understand the method to efficiently reduce the total perimeter count using adjacency checks, improving your problem-solving skills for matrix-related coding challenges in JavaScript.
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. ...
