🚀 Day 5 of Educative’s 30-Day Coding Challenge 🧩 Problem: Loud and Rich 💡 Approach: 🔹 Model the problem as a graph, where an edge y → x means y is poorer than x. 🔹 Build a reverse graph to easily traverse from a person to all richer individuals. 🔹 Use DFS with memoization to find, for each person, the quietest individual among themselves and all richer people. 🔹 Compare quietness levels during traversal to update the answer efficiently. 🎯 Takeaway: This problem beautifully combines graph traversal and dynamic programming (memoization) — showcasing how exploring relationships and caching results can simplify complex dependency problems. #30DaysofCode #Educative Educative #CodingChallenge #Consistency #Java #ProblemSolving #GraphAlgorithms #LearningEveryday

🚀 Day 7 of Educative’s 30-Day Coding Challenge 🧩 Problem: Convert Sorted Array to Binary Search Tree 💡 Approach: 🔹 Use a divide-and-conquer strategy to maintain BST balance. 🔹 Choose the middle element of the current subarray as the root node. 🔹 Recursively build the left subtree from the left half and the right subtree from the right half. 🔹 Base case: when left > right, return null. 🎯 Takeaway: Balanced trees are all about symmetry and structure — a great reminder that the right balance can make any system efficient and scalable. 🌱 #30DaysofCode #Educative Educative #CodingChallenge #Consistency #Java #ProblemSolving

Day 9 of #11Days11MiniProjects ⏰ Today's project: Study Break Reminder This project gently reminds users to take care of themselves while studying or coding. You enter how long you’ve been studying, and the program gives a random reminder — like “stretch your arms,” “get some water,” or “take a walk.” ☕ 💡 What I practiced today: • Arrays to store random reminders • Random class for variety • If-else logic for short vs. long breaks • Building user-friendly console interactions #Java #CodingChallenge #MiniProjects #Productivity #SelfCare #LearningByDoing #WomenInTech #11Days11MiniProjects #MindfulCoding

🚀 Day 57 of My LeetCode Journey 🚀 🔹 Today I solved Longest Common Prefix. Key Idea: To find the longest common prefix in a list of strings, we assume the first string as the prefix and gradually shrink it while checking with every other string. The moment a string doesn't start with the prefix, we trim the prefix until it matches — or becomes empty. 💡 What I learned: String operations like startsWith() can simplify logic. Sometimes, a simple greedy shrinking approach performs better than overthinking the solution. Clean code > complex code. 🧠 Takeaway: Break the problem into smaller checks. Don’t force complexity when simplicity solves it efficiently. Here’s the mindset: ➡️ Small progress every day still counts as progress. ➡️ Consistency beats intensity. #100DaysOfCode #leetcode #codingjourney #java #programming #learning

🚀 Sharpening My DSA Skills with Java on LeetCode Lately, I’ve been consistently solving problems on LeetCode, focusing on enhancing my problem-solving, logical thinking, and Java programming skills. 💻 Each challenge helps me approach problems more efficiently and think beyond conventional logic. Here are a few recent problems I worked on 👇 🔹Maximum Product of Three Numbers 🧠 Approach: Sort the array and consider two possibilities — Product of the three largest numbers Product of the two smallest (negative) numbers with the largest number Then, take the maximum of both results. 🔹Minimum Index Sum of Two Lists 🧩 Approach: Compare all common elements between both lists and calculate their index sums. Track the minimum index sum and update the result list dynamically. 🔹Set Mismatch 📊 Approach: Use a HashMap to detect the duplicate number. Then iterate through the range 1 to n to find the missing one not present in the map. 💡 Key Takeaway: Each problem refined my understanding of data structures, algorithm design, and optimization — all essential for writing cleaner and efficient Java code. 🚀 👨💻 Check out my complete DSA journey on LeetCode: 👉 leetcode.com/u/amans_01/ #Java #LeetCode #DSA #ProblemSolving #CodingJourney #SoftwareDevelopment #LearningEveryday #JavaDeveloper
