DIY: Shortest Bridge
Explore how to solve the shortest bridge problem by transforming a binary grid with two islands. Learn to implement an algorithm in Swift that calculates the minimum zeros to flip to connect these islands. This lesson helps you build skills in grid traversal and problem decomposition relevant for 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. ...
