📅 Day 51 of #100DaysOfCode Problem: Number of Substrings That Satisfy (LeetCode 3280) Approach: 1️⃣ Precomputed cumulative counts of 1s using a prefix sum array. 2️⃣ For each substring [i...j], calculated both the number of 0s and 1s. 3️⃣ Used a smart optimization: If (zero² > one), skip forward — those substrings can’t satisfy the condition. If (zero² == one) or (zero² < one), count and move ahead efficiently. 4️⃣ This drastically reduced redundant iterations compared to a naïve O(n³) brute force. #100DaysOfCode #LeetCode #DSA #ProblemSolving #Cplusplus #CodingChallenge #Algorithms #MathLogic #BinaryString #Programming #DeveloperLife #CodingJourney #CodeNewbie #DailyDSA #SoftwareEngineering #KeepLearning #GrowthMindset #Motivation #TechCommunity

📅 Day 32 of #100DaysOfCode Problem: Design HashSet (LeetCode 705) Approach: 1️⃣ Used a boolean vector of fixed size (1,000,001) to represent presence or absence of elements directly by index. 2️⃣ add(key) marks the key as true, meaning it’s present in the set. 3️⃣ remove(key) simply resets the value to false. 4️⃣ contains(key) checks presence in O(1) time using direct indexing — super efficient and clean! #100DaysOfCode #LeetCode #DSA #ProblemSolving #Cplusplus #CodingChallenge #HashSet #DataStructures #Algorithms #CodeNewbie #Programming #DeveloperLife #SoftwareEngineering #LearningInPublic #TechCommunity #KeepLearning #CodingJourney #Motivation #Efficiency

🔥 LeetCode POTD: Number of Substrings With Only 1s Today’s question was actually on the easier side… once you notice the key detail: it’s a binary string 👀. Here’s how my thought process went ⬇️ At first, I considered generating all substrings and then checking which ones contain only 1s. But of course… generating + checking = ❌ higher time complexity, which breaks the constraints. Not ideal. Then I took a step back and realized: 👉 Since it's a binary string, the substrings made of only 1s form clear continuous blocks. 👉 For each block of consecutive 1s of length k, the number of valid substrings is: k × (k + 1) / 2 ✨ Using this pattern, the whole problem can be solved in O(n) time. Dropped my solution in the image below 📸 Would love to hear how you approached it! 😄💬 #leetcode #leetcodechallenge #dsa #coding #programming #problemsolving #binarystrings

On Day 286 of my #300daysofcode challenge, I'm sharing my solution to LeetCode Problem 3461, "Maximum Length of Semi-Decreasing Subarrays." This problem is a good reminder that a simple brute-force approach is often the most direct and effective solution for smaller constraints or as a foundational step before optimization. My video provides a clear walkthrough of this logical method. #DataStructures #Algorithms #LeetCode #CodingInterview #Programming #ProblemSolving #300daysofcode

🔥 Day 70 of #100DaysOfCode 🔥 💡 Problem: Number of Steps to Reduce a Number to Zero – LeetCode ✨ Approach: A simple while loop logic — divide the number by 2 if it’s even, else subtract 1. Repeated until it hits zero. Clean, elegant, and lightning fast! ⚡ 📊 Complexity Analysis: Time Complexity: O(log n) – each division by 2 halves the number Space Complexity: O(1) – constant space ✅ Runtime: 0 ms (Beats 100%🔥) ✅ Memory: 41.95 MB 🚀 Key Takeaway: Sometimes, brilliance lies in simplicity — clear logic, powerful performance! #LeetCode #100DaysOfCode #ProblemSolving #CodingChallenge #Programming #DSA #LogicBuilding #Efficiency #CodeDaily #DeveloperJourney

The scariest bug in production? Accidentally exposing sensitive data! Don't just hope you filtered your objects. Enforce it at the type level! Here's how TypeScript's Pick utility type acts as your security guard. It lets you create a "safelist" of properties. #code #coding #programming #softwareengineering

🐧 Liskov Substitution Principle (LSP) — the third of the SOLID principles! 🧠 Definition: “If a class (subclass) inherits from a base class, it should be able to replace the base class without altering the correctness of the program.” In simple terms — 👉 A subclass should behave like its parent class — without breaking existing functionality. 🐦 Example (from the image): If a “Bird” class can fly, all its subclasses (like Sparrow) should also fly. But if you add a “Penguin” subclass — which can’t fly — it violates the Liskov principle. 🐧💥 This principle reminds us: inheritance isn’t just about sharing structure — it’s about maintaining behavior! ⚙️ #SOLIDPrinciples #LiskovSubstitutionPrinciple #CleanCode #SoftwareDesign #OOP #Programming #Developers #CodeSmart #LearnWithFun
