3598. Longest Common Prefix Between Adjacent Strings After Removals| LeetCode Weekly Contest 456

In this video, we solve LeetCode Problem 3598 - Longest Common Prefix Between Adjacent Strings After Removals, which is a Medium level string problem that challenges your understanding of string prefixes and smart precomputation!

💡 Problem Summary:
Given an array of strings, for every index i, remove the element at i and find the maximum common prefix between all adjacent pairs of the remaining strings. Return the list of results for each i.

📌 What you’ll learn:

How to compute common prefix efficiently between two strings

Smart use of precomputation to avoid redundant recalculations

Optimization using max prefix tracking to handle removal scenarios

⚙️ Approach:

Precompute prefix lengths for adjacent string pairs

Track top two prefix values with indices

For each removal, smartly decide between recalculating and using precomputed values

🧠 Time Complexity: O(N * L), where L is the average length of strings

🛠️ Language Used: C++
