Mirror Distance Problem: Computing Absolute Digit Difference

Solved the Reverse Integer problem without using any built-in functions 💻 Implemented a digit-by-digit reversal approach while carefully handling overflow using boundary checks. This ensures the solution is both safe and efficient. 🔹 Time Complexity: O(log n) 🔹 Space Complexity: O(1) Glad to see it pass all test cases with optimal performance 🚀 Sometimes, sticking to fundamentals is the best way to strengthen problem-solving skills. #Coding #DataStructures #Algorithms #ProblemSolving #CProgramming #LeetCode

Vector indexes don't have to break the bank. This video breaks down DiskBBQ — a disk-first vector index that keeps large embedding collections on disk, minimizes RAM usage, and preserves query performance so your vector DB costs don't scale linearly with size. Short, practical explainer with architecture highlights and benchmarks. Read more: https://lnkd.in/efQhhz7F #programming #ai #database https://lnkd.in/eG-yVXbg

Cycle Sort is not just another sorting algorithm, it is provably impossible to do fewer writes. Period. Cycle Sort follows where each element belongs, places it, picks up the displaced one, and follows that element. It continues chain after chain until every cycle closes. This is group theory disguised as a sorting algorithm. By minimizing writes to memory, Cycle Sort achieves the theoretical lower bound, making it optimal for scenarios where write operations are expensive, such as flash memory or EEPROM storage. Every element moves directly to its final position with no unnecessary swaps, proving that sometimes the most elegant solution is also the most mathematically efficient. #CycleSort #Programming #CodingLife #TechEducation #Algorithms #SortingAlgorithm #GroupTheory #OptimalAlgorithm #MemoryEfficient #ComputerScience #WriteOptimized #AlgorithmDesign #Coding #Developer #TechLearning #DataStructures #ProgrammingLife #CodeSmart #AlgorithmArt #ProvablyOptimal

“Why does this traversal not need a stack?” 🧠 Morris Traversal (Inorder) A way to traverse a binary tree using O(1) space. No recursion. No stack. Just smart use of pointers. ⚡ How it works: → If left is NULL → visit, go right → If left exists → find inorder predecessor → Create a temporary link (predecessor → current) → Move left → On return → remove link, visit, go right 💡 Core idea: We don’t use extra space… we reuse NULL pointers as a return path. 🎯 Conclusion: • Same traversal • Zero extra space • Deeper understanding of trees Took me a few dry runs to really get it. Did this concept click for you instantly or after struggle? 👀 #DataStructures #Algorithms #BinaryTree #CodingInterview #SoftwareEngineering  #LearnInPublic #ProblemSolving #DeveloperJourney #TechLearning #CodingJourney  #DSA #CodeNewbie #Programming #ComputerScience #Coding

Recover the Tree ?? by providing water! Approach (Recover BST) Do inorder traversal (BST should be sorted) Track previous node If order breaks (prev > current), it’s a violation First violation: first = prev middle = current Second violation (if exists): last = current Time Complexity: O(n) → you traverse all nodes once using inorder Space Complexity: O(h) → recursion stack (h = height of tree) Worst case (skewed tree): O(n) Best case (balanced tree): O(log n) #LeetCode #DSA #DataStructures #Algorithms #Coding #Programming #binarysearchtree

💡 DSA Day 216 ✅ ❓ Shortest Distance to Target String in a Circular Array 🔍 The Challenge: In a circular array of size n, distance isn’t always straight. You have to consider both directions: Direct distance: |i - start| Wrap-around distance: n - |i - start| ✨ The Insight: Take the minimum of both: min(direct, wrap-around) This keeps the solution clean and efficient: ⏱️ Time Complexity: O(n) 📦 Space Complexity: O(1) #Coding #DataStructures #CPP #LeetCode #ProblemSolving #ShortestDistancetoTargetStringinaCircularArray

📌 Day 1/100 – #100DaysOfDSA Started my journey today with a classic problem from LeetCode: 🔍 Problem: Remove Duplicates from Sorted Array 🧠 What I learned: How to use the two-pointer technique efficiently Instead of extra space, we can modify the array in-place Helps reduce time complexity to O(n) and space to O(1) ✅ Solution Approach: Used two pointers — one to track unique elements and another to traverse the array 👣 Whenever a new unique element is found, it gets placed in the correct position. 💡 Key Insight: When the array is sorted, duplicates are always adjacent — making this problem much simpler! ⚡ Takeaway: Two-pointer technique is powerful for array problems — definitely a pattern to remember.
