Island Perimeter

Explore methods to calculate an island's perimeter within a grid by applying matrix traversal and problem-solving techniques. Understand how to identify connected land cells and compute boundaries, enhancing your skills for coding interviews focused on matrices.

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.

  • The grid is rectangular, and each cell is a square with a side length 1.

Your task is to calculate the perimeter of the island.
