🧠 Coding Challenge: Merge Sorted Arrays Here’s a simple-looking problem that tests your logic and attention to detail 👇 You are given two sorted arrays: let arr1 = [1, 5, 8, 9] let arr2 = [3, 4, 6, 10] 🎯 Task: Merge these two arrays into a single sorted array. Sounds easy, right? But there’s a catch… 👀 Think about: - How will you compare elements efficiently? - What happens when one array finishes before the other? - Are you sure your loop covers all cases? ⏳ Take a moment and try solving it yourself before scrolling further. 💬 If you get stuck or want to verify your approach, check the answer in the comments! #JavaScript #CodingChallenge #DSA #Programming #WebDevelopment

LeetCode Day 3 : Problem 189 (Rotate Array) Just solved another LeetCode problem. It was "Rotate Array", sounds simple, right? But here's what I actually learned: My first solution used pop() and unshift() in a loop. It worked but was O(n×k), every unshift shifts the entire array one step, and I was doing it k times. On a large array that's painfully slow. I forgot to handle the case where k is larger than the array length. Rotating a 3 element array by 6 steps is the same as rotating by 0. One line fix, k = k % nums.length. Always think about edge cases before submitting. The optimal fix? The Reverse Trick. Reverse the entire array, then reverse the first k elements, then reverse the rest. Three reverses. One pass. O(n) time, O(1) space. Hard to believe it works until you trace through it yourself. Six problems in. The pattern is clear, there is always a brute force solution and a clever one. The clever one usually involves looking at the problem from a completely different angle. The real lesson? If your solution involves a loop inside a loop, always ask yourself if there is a smarter way. #DSA #LeetCode #JavaScript #CodingJourney #Programming

The new keyword looks simple… but most people use it without knowing what it actually does 👀 That’s exactly where confusion starts. Why does a function suddenly create objects? Where does this point? And how do methods magically appear? 👉 It’s all because of new. In this blog, I’ve explained: What new actually does behind the scenes How constructor functions create objects How objects link to shared methods (prototype) Why everything breaks without new Kept it simple, with step-by-step explanation and examples ✨ 🔗 Read here: https://lnkd.in/dyZwek-x Would love your feedback 🙌 Next: Constructor Functions or this keyword? #javascript #webdevelopment #programming #coding

LeetCode Day 2 : Problem 26 (Remove Duplicates from Sorted Array) Just solved my third LeetCode problem. It was "Remove Duplicates from Sorted Array", sounds straightforward, right? But here's what I actually learned: My first instinct was to use .splice() inside a loop. It works, but every splice shifts all elements after it, meaning for a large array you're doing that shift hundreds of times. Slow. I also added .sort() at the top — but the problem already guarantees a sorted array. Sorting again is just wasted work. Always read the constraints. The fix? Two Pointer pattern again. Since duplicates are always next to each other in a sorted array, just compare each element with the previous one. One pass, no splicing, no sorting. Three problems in. The Two Pointer pattern has shown up in all three. Same idea, slightly different condition each time. The real lesson? Before writing code, read the constraints carefully. They often tell you exactly what you don't need to do. #DSA #LeetCode #JavaScript #CodingJourney #Programming

🚀 Day 568 of #750DaysOfCode 🚀 🔍 Problem Solved: Two Furthest Houses With Different Colors Today’s problem looked simple at first, but it had a nice twist that tested observation skills more than brute force thinking. 💡 Key Insight: To maximize the distance between two houses with different colors, we don’t need to check all pairs. The answer will always involve either: the first house, or the last house Why? Because the maximum distance comes from the edges of the array. ⚡ Approach: Compare every house with the first and last house If colors are different → calculate distance Keep track of the maximum distance 🧠 Optimization: Instead of an O(n²) brute-force approach, we can solve this in O(n) time with constant space. 📈 Complexity: Time: O(n) Space: O(1) ✨ Takeaway: Sometimes the best solution isn’t about trying everything — it’s about spotting the right pattern. #LeetCode #Java #DSA #CodingJourney #ProblemSolving #100DaysOfCode #Programming #Tech #LearningEveryday

Recently started learning Go. My current approach: solve the problem in JavaScript first, then implement the same solution in Go. Why? Because it lets me separate algorithmic thinking from learning a new syntax. It’s a simple process, but so far it feels effective: understand the logic first, then strengthen Go through practice. Small steps, but consistent ones. #GoLang #Go #Programming #SoftwareDevelopment #BackendDevelopment #Coding #JavaScript

LeetCode Day 5 : Problem 122 (Best Time to Buy and Sell Stock II) Just solved another LeetCode problem. It was "Best Time to Buy and Sell Stock II", a follow up to yesterday's stock problem, right? But here's what I actually learned: My first instinct was to track the minimum price just like the previous problem. It worked, but I was overcomplicating it. The simpler insight? Since you can buy and sell on the same day, you don't need to track the minimum price at all. Just grab every upward movement between consecutive days. If today is higher than yesterday, add the difference to your profit. That's it. Same problem structure, completely different angle. The lesson, don't carry assumptions from one problem into the next. Each problem deserves a fresh look. Eight problems in. The greedy approach keeps showing up, sometimes the optimal solution is just grabbing every small win as you go instead of looking for the perfect moment. The real lesson? Simpler code is almost always better code. If you need to track extra variables, ask yourself if you actually need them. #DSA #LeetCode #JavaScript #CodingJourney #Programming

🚀 Code 2 – #50LeetCodeChallenge Problem: "Longest Common Prefix" Given an array of strings, find the longest common prefix shared among all strings. If no common prefix exists, return an empty string "". 💡 Approach: Start with the first string as the prefix and compare it with the remaining strings. Gradually reduce the prefix until it matches the beginning of each string. 📚 Key Takeaway: String comparison and iterative reduction help efficiently solve prefix-based problems with optimal performance. #LeetCode #Java #Coding #ProblemSolving #Strings #Programming
