Grokking the Coding Interview Patterns in Go

Solution: Number of Islands

Explore how to solve the Number of Islands problem using the Union Find pattern in Go. This lesson guides you through counting connected land cells as islands by merging adjacent cells efficiently, helping you understand and implement a common algorithmic pattern useful for coding interviews.

We'll cover the following...

Statement

Let’s consider a scenario with an (m×n)(m \times n) 2D grid containing binary numbers, where '0' represents water and '1' represents land. If any '1' cells are connected to each other horizontally or vertically (not diagonally), they form an island. Your task is to return the total number of islands in the grid.

Constraints:

  • 1≤1 \leq grid.length ≤50\leq 50

  • 1≤1 \leq ...
