Solution: Island Perimeter
Understand how to calculate the perimeter of an island within a grid by iterating through each cell, adding edges for land cells, and subtracting shared edges with adjacent cells. This lesson helps you apply matrix traversal and conditional checks to solve spatial problems efficiently.
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. ...
