Greedy Scheduling Solution for Minimum Machines

🚀 [Day 15/30] Coding Challenge with @Educative.io 💻 💡 Problem: Subarrays with K Different Integers Today’s challenge was a great exercise in sliding window + counting techniques. The goal was to count subarrays that contain exactly K distinct integers. The key insight that made this problem click: 👉 Counting “exactly K” is easier if we count (at most K) − (at most K − 1). My approach: 1️⃣ Used a sliding window with a frequency map to count subarrays with at most K distinct integers 2️⃣ Reused the same logic to compute at most (K − 1) 3️⃣ Subtracted the two results to get exactly K distinct subarrays This avoided nested loops and kept the solution in O(n) time. ✨ Small win: Turning a complex “exactly” condition into two simpler “at most” problems made the solution both elegant and efficient. 🔍 Key Learnings: Sliding window patterns are extremely powerful for subarray problems Breaking problems into reusable components simplifies logic “Exactly K” often hides a smart counting trick #30DaysOfCode #Day14 #CodingChallenge #Educative #DSA #SlidingWindow #HashMap #Algorithms #JavaScript #ProblemSolving #InterviewPrep #SoftwareEngineer #LearningInPublic #TechCareers #KeepCoding

🚀 [Day 17/30] Coding Challenge with @Educative.io 💻 💡 Problem: Split Array Largest Sum Today’s challenge was an interesting mix of binary search + greedy validation. The goal was to split an array into m subarrays such that the largest subarray sum is minimized. The key insight: 👉 If we fix a maximum allowed subarray sum, we can greedily check whether the array can be split into at most m parts. My approach: 1️⃣ Set the search space between max(nums) and sum(nums) 2️⃣ Used binary search to guess the optimal maximum sum 3️⃣ For each guess, greedily counted how many subarrays were needed 4️⃣ Adjusted the search range based on feasibility This turned a complex optimization problem into a clean decision problem.| ✨ Small win: Realizing how “minimize the maximum” problems often map directly to binary search was a big confidence booster. 🔍 Key Learnings: Binary search isn’t just for sorted arrays Greedy checks pair perfectly with binary search Optimization problems often hide feasibility checks #30DaysOfCode #Day17 #CodingChallenge #Educative #DSA #BinarySearch #Greedy #Algorithms #JavaScript #ProblemSolving #InterviewPrep #SoftwareEngineer #LearningInPublic #TechCareers #KeepCoding

✨TypeScript's any vs unknown — Which one do you use? Most of us grab any for quick fixes, but it can hide bugs until runtime. unknown forces validation, making your code safer from the start. It's not about more typing. It's about writing smarter, more reliable code. 👉 Want the simple breakdown? I covered any, unknown, null, and undefined with clear examples here: https://lnkd.in/g9i8xSWr #TypeScript #WebDevelopment #ProgrammingTips #Coding #JavaScript #FullStackDevelopment

Learning to code feels exciting. Writing code teaches patience. 😄 Tutorials look simple, but real coding comes with bugs, errors, and a lot of problem-solving. And that’s okay—because every error is a step closer to mastery. Keep learning. Keep building. Keep debugging. 🚀 #CodingJourney #LearningToCode #DeveloperLife #ProgrammingHumor #SoftwareDevelopment #Debugging #TechLife

🚀 [Day 18/30] Coding Challenge with @Educative.io 💻 💡 Problem: Invert Binary Tree Today’s challenge was a classic tree problem — inverting a binary tree by swapping the left and right children of every node. The logic was simple yet powerful: 👉 Traverse the tree and swap left ↔ right at each node. I approached it using recursion: 1️⃣ Swap the left and right child 2️⃣ Recursively apply the same logic to both subtrees This can also be solved iteratively using BFS or DFS, but recursion keeps the solution very clean and readable. ✨ Small win: Problems like this remind me how elegant tree recursion can be — minimal code, clear intent. 🔍 Key Learnings: Tree transformations are often recursive by nature Preorder traversal works well for structural changes Simple problems still reinforce core fundamentals #30DaysOfCode #Day18 #CodingChallenge #Educative #DSA #BinaryTree #Recursion #Algorithms #JavaScript #ProblemSolving #InterviewPrep #SoftwareEngineer #LearningInPublic #TechCareers #KeepCoding

❗Don't Waste Your Time Writing Tests ❗ Testing is for those who lack confidence. If your code works on your machine, it’s good enough for the world. Trust in your infallible programming skills. #TipOfTheDay

In coding, there’s a simple rule that many beginners overlook: “The simplest solution is often the best solution.” It’s tempting to write clever, complex code to show skills. But in reality: Simple code is easier to read Simple code is easier to debug Simple code lasts longer Think of it like writing a recipe. A complicated recipe might impress once, but a simple, clear one is usable and memorable every time. So next time you write a function or design a component, ask yourself: Can I make this simpler without losing functionality? Your future self (and your team) will thank you. 😌 #ProgrammingTips #CleanCode #DevHonor #SoftwareDevelopment #CodingWisdom #CodeBetter #TechTips #SoftwareEngineering #CodingLife #WebDevelopment #FrontendDevelopment #DeveloperMindset #TechLearning

The Bitter Truths Every Beginner Coder Needs to Hear Coding isn’t as glamorous as it looks. Here’s what I’ve learned the hard way: 1. It’s frustrating. Hours can go by debugging errors you barely understand. 2. Tutorials don’t equal mastery. Watching someone code is not the same as doing it yourself. 3. Progress is slow. Real growth comes in small, consistent wins. 4. Consistency > motivation. Motivation fades, but showing up daily builds skill. 5. The learning curve never ends. Even experienced developers face challenges constantly. 6. Embrace the struggle—it’s how you become a better problem-solver, thinker, and coder. CTA: Start small, stay consistent, and don’t fear the bugs. Every fix is progress. #CodingLife #WebDevelopment #JavaScript #DeveloperJourney #Programming #TechCareers #CareerGrowth #LearnToCode #CodeBetter #doinghardthings

Cursor feels less like a tool and more like pair programming with an incredibly fast, knowledgeable colleague. As a VSCode fork, it seamlessly integrates into a developer's workflow. Using it feels like a constant conversation. It's not just finishing sentences; it's writing entire functions. Cursor's composer feature lets you write a single prompt to coordinate changes across different files, but it's not perfect. It can lose the plot on massive system-wide refactors and the credit system can get expensive for power users. #AIcoding #VSCode #productivity #softwaredevelopment
