Have you solved your LeetCode problem today? 👀 🧠 Problem: Find Lexicographically Smallest String from LCP Matrix 💡 Approach (pseudo code): 1. Use Union-Find to group indices where lcp[i][j] > 0 2. Each connected component must have the same character 3. Assign smallest lexicographic characters to each component 4. Build the result string 5. Validate using LCP computation 6. Return result or "" if invalid ⚡ Optimization: Used path compression + union by rank HashMap for component → character mapping Can further optimize validation using DP (O(n²)) Drop your approach below ⬇️ #LeetCode #Coding #100DaysOfCode

Day 10 of solving LeetCode Solved: • Subarray Sum Equals K • Longest Consecutive Sequence Learned how powerful HashMap and HashSet can be for optimizing solutions from brute force to O(n). These problems really improved my understanding of patterns in arrays. #LeetCode #DSA

✅Day 22/100 – #100DaysOfDSA Solved: - Minimum Absolute Difference Between Two Values (LC Biweekly Contest) - Could think of the approach for the 2nd ques as well but could not code it properly. Turned out it involved quite much of maths. #DSA #LeetCode #100DaysOfCode📷

I have an array of numbers. You can pick elements, but never pick two adjacent ones. Your goal is to maximize the sum. What problem is this, and what’s the approach? #coding #dsa #leetcode #ai #programming

Solved a Biweekly contest problem today....Minimum Absolute Difference Between Two Values. O(N) approach: just track latest index of 1 & 2 and keep updating the min difference. Pretty straightforward, give it a try 👀 #softwareengineering #leetcode #dsa #codinga
