Debugging: The Key to a Strong Engineer

🚀 Day 30/60 — LeetCode Discipline Problem Solved: 3Sum Closest Difficulty: Medium Today’s problem pushed beyond exact answers and focused on finding the closest possible sum to a given target — a subtle yet powerful variation of the classic 3Sum problem. By sorting the array and using a two-pointer approach, the solution efficiently explores combinations while continuously updating the closest result. This problem highlights how small modifications in logic can significantly change the nature of a problem — from exact matching to optimal approximation. 💡 Focus Areas: • Strengthened two-pointer technique • Practiced working with sorted arrays • Improved handling of optimization conditions • Learned to track and update closest values dynamically • Reinforced problem-solving under constraints ⚡ Performance Highlight: Achieved efficient runtime with optimized traversal. Not every problem asks for perfection — sometimes, the goal is to get as close as possible. #LeetCode #60DaysOfCode #100DaysOfCode #DSA #TwoPointers #Algorithms #ProblemSolving #CodingJourney #SoftwareEngineering #Java #Developers #Consistency #TechGrowth #LearnToCode

I recently encountered an ambiguous mapping error while working on a REST API. The stack trace was overwhelming, but the message was straightforward : I had two different methods competing for the same URL and HTTP verb. The issue happened because I had two methods, createEmployee and createNewEmployee, both annotated with @PostMapping, along with @RequestMapping on the controller class. Spring couldn't determine which method to use to handle the request. To resolve this, it's essential to keep the endpoints unique or utilize different HTTP methods to maintain organization.

🚀 Day 29/60 — LeetCode Discipline Problem Solved: Longest Common Prefix Difficulty: Easy Today’s problem focused on identifying the longest common starting pattern across multiple strings — a classic exercise in string comparison and iteration. The approach involved checking characters position by position across all strings until a mismatch is found. This reinforces how simple iterative logic can elegantly solve problems involving multiple inputs. It’s a reminder that sometimes, clarity in approach matters more than complexity in code. 💡 Focus Areas: • Strengthened string traversal techniques • Practiced comparing multiple inputs efficiently • Improved understanding of edge cases (empty strings, mismatch handling) • Reinforced early stopping conditions for optimization • Focused on clean and readable logic ⚡ Performance Highlight: Achieved efficient runtime with minimal overhead. Finding common ground across multiple inputs is not just a coding skill — it’s a pattern recognition mindset. #LeetCode #60DaysOfCode #100DaysOfCode #DSA #Strings #Algorithms #ProblemSolving #CodingJourney #SoftwareEngineering #Java #Developers #Consistency #TechGrowth #LearnToCode

Most people think coding is about writing logic. But it's something deeper… It’s about thinking clearly when things don’t work. I spent hours debugging a small issue, not because it was hard, but because my thinking was messy. The moment I slowed down, broke the problem and questioned every assumption… The solution appeared in minutes💡 Good developers don’t just code fast. They think better. And that’s what I’m working on every single day. #SoftwareDevelopment #CodingJourney #ProblemSolving #Java #Learning

🚀 Solved Linked List Cycle Detection using Fast & Slow Pointers Used Algorithm are: - Slow pointer moves 1 step - Fast pointer moves 2 steps - If they meet → cycle exists To find cycle start: - Move slow to head - Move both one step → meeting point = cycle start ⚡ Time: O(n) | Space: O(1) #DSA #LinkedList #Java #LeetCode #Coding

🚀 Day 561 of #750DaysOfCode 🚀 📌 Problem: Minimum Distance to the Target Element Today’s problem was simple yet a great reminder of how powerful basic iteration can be when applied correctly. 🔍 The task was to find the minimum distance between a given start index and any index i such that nums[i] == target. 💡 Key Insight: Instead of overthinking, just iterate through the array and track the minimum value of |i - start| whenever the target is found. Clean, efficient, and effective. 🧠 What I Learned: Sometimes brute force with clarity is the best solution Always look for opportunities to minimize operations with simple logic Writing clean and readable code matters as much as solving the problem ⚡ Approach: Traverse the array Check for target Update minimum distance ⏱️ Complexity: Time: O(n) Space: O(1) 💻 Consistency is key. Small steps every day build strong problem-solving skills over time. #leetcode #dsa #programming #java #coding #developers #softwareengineering #100daysofcode #codingjourney #tech #learning #growth

From basics to logic — today was all about Yesterday's control and flow. Day 02 of my journey towards becoming a Backend Engineer — and today felt like a real step forward. After covering the fundamentals yesterday, I moved into understanding how programs actually make decisions and repeat tasks. Here’s what I covered today: – Conditional Statements (if, else-if, switch) – Loops (for, while, do-while) – Nested conditions and loops – Control flow and execution logic This is where coding starts to feel less like syntax and more like problem solving. What stood out today was how important logic building is. You can know all the syntax in the world, but without clear thinking, writing efficient code becomes difficult. Loops, especially, made me realize how powerful repetition is when used correctly — and how easily it can go wrong if not understood properly. Also started paying attention to: – Writing cleaner conditions – Avoiding unnecessary iterations – Thinking about edge cases It’s still the basics, but these are the foundations everything else will stand on. 📍 Day 02 of #BecomingABackendEngineer What’s one concept in loops or conditions that took you time to truly understand? #Java #BackendDevelopment #LearningInPublic #Programming #StudentDeveloper #ConsistencyIsKey #TechJourney #BecomingABackendEngineer #DSAToMLJourney

🐛 Debugging is a Superpower Every Developer Needs Real development is not writing code… It’s fixing what breaks. One thing that helped me a lot: 👉 Don’t panic. Read the error carefully. ✔ Check logs ✔ Reproduce issue ✔ Break problem into smaller parts Most bugs are simple — we just overthink them. Great developers = great debuggers. Agree? 👇 #Debugging #Java #Developers #ProblemSolving

A small mistake that cost me hours of debugging  Recently, I faced an issue in backend code that looked simple at first.  But it took hours to fix because I missed one thing:   Understanding the complete flow before debugging  What I learned:   ✔ Trace the full request flow   ✔ Check logs before jumping into code   ✔ Avoid assumptions  Debugging is not about fixing fast, it’s about understanding deeply.  Have you faced similar situations?  #Java #BackendDevelopment #Debugging #SoftwareEngineering

#Day357 of #1001DaysOfCode LeetCode Daily Challenge Problem: Decode the Slanted Ciphertext (LeetCode 2075) 💡 Approach: The encoded string represents a matrix filled row-wise. I traversed the matrix diagonally (top-left to bottom-right) by converting 2D indices into a 1D string index. Finally, removed trailing spaces to get the correct decoded message.
