LeetCode 191: Number of 1 Bits - Bit Manipulation Basics

Solved LeetCode: Power of Two using Bit Manipulation Learned how to efficiently check whether a number is a power of 2 using binary properties. A number is a power of two if it has only one set bit in its binary representation. Used the trick: n > 0 && (n & (n - 1)) == 0 Optimized solution with: Time Complexity: O(1) Space Complexity: O(1) This problem helped me understand bit manipulation, binary concepts, and optimized checking techniques https://lnkd.in/dFdQhMmS GitHub Repo: https://lnkd.in/gg4daDpn #day10 #DSA #Cpp #LeetCode #Coding #Programming #Learning #ProblemSolving #BitManipulation

Back to fundamentals: Introduction to Programming. Today’s learning reminded me that coding is more than syntax — it is the language through which humans communicate instructions to machines. From low-level concepts to high-level languages, from compilers to object code, every modern system is built on these foundations. To truly build, test, debug, and innovate, one must know what is happening beneath the surface. Sometimes progress means going back to the basics and understanding how things truly work. Strong roots. Better growth. #Programming #CodingJourney #ComputerScience #CLanguage #TechLearning #DeveloperMindset #LearnToCode #Foundations #CSBasics #GrowthMindset

Day 99/100 – DSA Challenge 🚀 Topic: Variable Window Key Learning: So one of the most powerful techniques in problem-solving especially in DSA is the Variable Window (Dynamic Sliding Window). What is it? A method where we use two pointers to create a window that expands and shrinks dynamically based on a condition. Why is it important? It helps reduce time complexity from O(n²) → O(n) in many problems involving arrays and strings GitHub: <https://lnkd.in/dtek96E3> #100DaysOfDSA #ProblemSolving #LinkedInLearning #clanguage #coding #programming #developer #softwareengnieer #datastructure

Today, recursion finally made sense to me — not as something to memorize, but something to truly understand. A small mistake taught me an important lesson: func(v1++, n); I assumed v1 would be incremented before the recursive call. But v1++ actually passes the current value first and increments afterward. Result? The same value kept getting passed repeatedly, leading to infinite recursion. The correction was simple: func(v1 + 1, n); or func(++v1, n); What really changed my understanding was visualizing the call stack: recursive calls keep stacking downward each function waits for the next call to finish code after the recursive call executes while the stack unwinds That moment when recursion finally “clicks” feels incredibly rewarding. #cpp #programming #recursion #coding #computerscience #developers

Leetcode daily - Day 3 🧠 Problem: (Isomorphic Strings) Check if two strings are isomorphic (one-to-one character mapping with order preserved). 💡 Approach: Used two hash maps to maintain mapping: s → t t → s If any mismatch occurs → return false, else true. 🔑 Key Learning: One-to-one mapping (bijection) HashMap usage in strings ⏱ Time Complexity : O(n) 💾 Space Complexity : O(1) ✨ Consistency is the key to mastering DSA! #LeetCode #DSA #CodingJourney #ProblemSolving #Consistency #Programming

One thing I learned during my coding journey: Knowing a programming language is not enough. Companies test your problem-solving ability, and that comes from Data Structures & Algorithms. Recently I started learning DSA in a structured way and the difference is huge. Instead of memorizing code, now I actually understand why the solution works.

The role of a 'second brain' is becoming increasingly defined, moving beyond mere data storage. While understanding the underlying architecture and learning the necessary layers is crucial, the days of solely memorizing syntax are numbered. Much of this can now be generated, though it may not always adhere to best practices. Even for new programming languages, the landscape is shifting towards understanding core concepts rather than rote memorization. #SoftwareDevelopment #Programming #FutureOfCode #TechTrends #Learning
