Solution: Island Perimeter
Understand how to solve the island perimeter problem by iterating through grid cells, identifying land connections, and calculating perimeter adjustments. This lesson teaches efficient matrix traversal and perimeter calculation techniques using constant space and linear time 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. ...
