DIY: Shortest Bridge

Explore how to find the minimum number of cells to flip in a grid to connect two islands using C#. Learn grid traversal techniques and understand problem constraints to implement an efficient shortest bridge solution in coding interviews.

Problem statement

You are given an n x n binary matrix grid containing 0s and 1s. Each cell in the grid represents either land or water. A cell with a value 1 represents land, while one with a value 0 represents water. A bunch of four-directionally adjacent cells with the value 1 constitutes an island.

There are exactly two islands in the grid. ...
