Solution: Island Perimeter
Explore how to determine the perimeter of an island in a grid by iterating through cells and adjusting for shared edges between adjacent land cells. Understand the step-by-step approach to calculate the total island perimeter using a matrix traversal method constrained by efficient time and space complexity.
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. ...
