Day 40 – MERN Stack 🌐 Topic: Js -> Memory game Learning how real products are built. 📸 Class 📝 Notes One day at a time. #WebDev #MERNStack #BuildInPublic

Day - 15 🚀 Graph - Shortest Path in Directed Acyclic Graph (DAG) With consistency in the 100 Days Challenge 💪 Learning with Rohit Negi (Coder Army) & Aditya Tandon 🙋 #Day15 #DSA #Graph #CodingChallenge #100DaysOfCode #Learning #ConsistencyWins

Day 08 of CSS Got hands-on with transform: translate() — positioning without reflow. translateX, translateY, translateZ → precise movement on GPU layer No layout shift. No margin hacks. Just performant motion. This is where animations stop being clunky and start feeling real.

The internet isn’t actually reliable. There’s no guarantee your data reaches its destination. No guarantee of order. No guarantee it won’t get lost. It’s all “best effort.” Protocols like TCP just fix the chaos behind the scenes. internet works by pretending it’s fine.

Day 24 – Java Interfaces Deep Dive Today I explored one of the most powerful concepts in Java — Interfaces 💡 Interface = Contract (what to do, not how to do) Default Methods → add functionality without breaking old code Functional Interface → backbone of Lambda Expressions Marker Interface → tagging mechanism (like Serializable) Supports Multiple Inheritance (huge advantage 🔥) Key takeaway: Interfaces help in writing clean, flexible & scalable code Teacher: @adityatandon02 Consistency in learning > Everything else. #Java #100DaysOfCode #Programming #CodingJourney #JavaDeveloper

Dream life 🙃

Guys 4 ki streak to tut gayi but lecture toh dekha tha ab aaj lecture 18 se start Kiya hai dekhte kitne lecture ho sakte aaj main @rohit_negi9 @adityatandon02 @CoderArmy

🚀 Solved: Minimum Absolute Difference in Sliding Submatrix (@LeetCode Daily) Extract k×k elements, sort, find min gap between consecutive distinct values. ✔ O(M×N×K²×log(K)) 🔥 #Day52/90 #LeetCode #DSA #Matrix #SlidingWindow #Sorting #BruteForce #ProblemSolving #CPlusPlus

Day 3 of my Java journey 💻☕ @adityatandon02 @CoderArmy Learned Java operators — arithmetic, unary, logical, and bitwise. Never understood this so clearly before, especially how values are stored in memory 🔍 #Java #Day3 #CodingJourney #Learning

Jai Shri Ram!🙏 Lecture 44: Stack+3 Problems 📦Stack Implementations: • Array (fixed size, fast) • Linked List (dynamic) • STL(built-in) 🔥Problems: ✅Stack Using Array ✅Insert at Bottom (recursion) ✅Reverse Array (two-pointer) LIFO fundamentals unlocked!💪 #StrikeBatch #DSA

Strike Day 65 | DSA Lecture 45 done Java lecture 22 done GenAi Lecture 27 done Genai : Build the deep learning -> learn and build every thing from scrach DSA: Make the Array Beautiful String Manipulation Minimum Add to Make Parentheses Valid Valid Parentheses Backspace String Compare print Bracket Number JAVA: toString(),equals(),hashCode(),getClass(),clone(),Finalize() Threads intro

Today's logs:- >office from 9am to 7:30pm >attended live DSA lecture by @rohit_negi9 , today was about problems on stack , forgot to take screenshot :( >solved make the array beautiful on gfg >solved string manipulation on gfg >reached 151 problems on @geeksforgeeks

Day 07 of CSS 🚀 Learned @keyframes animation — things are getting interesting now. Built a “Strike is Coming Soon” animation today. Not perfect yet, but I can control movement and timing. Consistency > perfection. #CSS #WebDevelopment #100DaysOfCode #Frontend #coderArmy🪖

@Akshat_Tiwari12 @rohit_negi9 Nice 👏 Keep learning.... Keep growing...... 🔥

Took a day off from college—and made it count. CSS Day 6 ✅️ Focused on building responsive websites . DSA Progress 📈 • Learned Aggressive Cows prob • Solved a related prob: Magnetic Force Between Two Balls #100DaysOfCode #WebDevelopment #CSS #DSA #CodingJourney
