Let me analyze the problem and the DSA pattern provided:

Problem: "Making A Large Island" (LeetCode 827)

• We have an n x n binary matrix grid
• We're allowed to change at most one 0 to be 1
• Return the size of the largest island after this change
• An island is a 4-directionally connected group of 1s

The proposed solution pattern is DFS with Connected Components Labeling, which makes sense for this problem:

1. Identify and label all existing islands using DFS
2. Keep track of each island's size in a hashmap
3. Iterate through all '0' cells and check if changing it to '1' would connect multiple islands
4. Calculate the resulting island size and find the maximum

Now, let me outline a solution approach in bullet points based on this pattern. I'll also analyze time and space complexity.
