🚀 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

#lec 45: Problems on stack. Strike DSA by @rohit_negi9 bhaiya. Qs 🔹Make The Array beautiful 🔹String manipulation 🔹Minimum Add to Make Parentheses Valid 🔹Valid Parentheses 🔹Backspace String Compare 🔹Print Bracket Number

🚀 Day 20 and 21 of Java @CoderArmy Today I understand the core concept ✅ System.out.println internals & System class ✅ Input/Output streams& hierarchy ✅ BufferedReader, Scanner ✅ Scanner vs BufferedReader ✅ Mutable & Immutable classes #Java #CodingJourney #100DaysOfCode

Just finished Lecture 24 of @CoderArmy's Java course 🚀 Key takeaway: ✅ Deep dive into Java Interfaces ✅ Functional & Marker Interfaces ✅ Interface inheritance ✅ Internal working youtu.be/YLLFHuStkW8?si… #Java #CoderArmy

#Lecture45 of STRIKE DSA by @rohit_negi9 Today Problems Covered:- 1. Make Array Beautiful. 2. String Manipulation. 3. Minimum Add to make valid parentheses. 4. Valid Parentheses. 5. Backspace string compare. 6. Print bracket number #strikecoderamy #dsaproblems #codingpractice

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

Day - 14 🚀 Graph Series Shortest Path in Undirected Graph Learning how to find the shortest path using BFS in an undirected graph 🔥 With Rohit Negi (Coder Army) & Aditya Tandon 100 Days Challenge Accepted 💪 #DSA #Graph #CodingChallenge #100DaysOfCode #Learning #BFS

Training a model from scratch in C++ 🚀 No libraries. Just understanding how it actually works: data → loss → gradients → weight updates After 500 epochs: w1 ≈ 4.89, w2 ≈ 2.94, b ≈ 4.94 (Expected: 5, 3, 4) This is where ML truly clicks 💡 #MachineLearning #CPP @CoderArmy

#Lecture28 of STRIKE GENAI by @rohit_negi9 Today Topic Covered:- Basic deep learning code to train the model to predict the output. #strikecoderamy #genAIcourse #deeplearning

Day 24 Done ✅ of JAVA Deep dive into JAVA Interfaces -What problem they solved, -Difference between Abstract classes and Interfaces, -Multiple Inheritance using Interfaces, -Default & Static methods in Interfaces, -Functional and Marker Interfaces.

New lecture uploaded🤍 Watch it: youtu.be/YLLFHuStkW8?si…
