Grokking the Coding Interview Patterns

Shortest Bridge

Explore how to solve the Shortest Bridge problem by identifying and connecting two islands in a binary grid. Understand problem constraints, develop strategies to flip the fewest water cells, and implement an optimal O(n²) time and space solution. This lesson builds problem-solving skills for 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 value of ...
