Grokking the Coding Interview Patterns in C++

Shortest Bridge

Explore how to determine the minimum number of zero cells to flip in a binary grid to connect two islands. Understand adjacency rules, matrix constraints, and implement an O(n²) solution to reinforce problem-solving skills in coding interviews.

We'll cover the following...

Statement

We are given an n×nn×n binary matrix grid containing 0s and 1s. Each cell in the grid represents either land or water. A cell with a value of 1 represents land, while a cell with a ...
