Max Consecutive Ones in Binary Array with K Flips

🚀 Turning a simple Java problem into a learning moment! Today I worked on a small but interesting problem: 👉 Find the absolute difference between a number and its reversed form. Leetcode problem: https://lnkd.in/g3wkXSyg 🔍 What this taught me: How to reverse a number using modulus (%) and division (/) Why storing the original value matters before modifying it How Math.abs() helps ensure the result is always positive 💡 Example: If n = 123 Reversed = 321 Absolute difference = |123 - 321| = 198 Sometimes, even small coding challenges sharpen problem-solving skills and reinforce core programming concepts. #Java #Coding #ProblemSolving #DSA #Programming #SoftwareDevelopment #Developers #CodingJourney #LeetCode

Reversed String in Java | Easy Logic + Coding 💡 Strong fundamentals are essential to become a confident developer. This example shows how String Reversal works using simple logic: • Start with a given string • Traverse the string from last character to first • Use loop or built-in methods • Form the reversed string Practicing these types of problems improves logical thinking and strengthens coding basics. 📊 Example Input : LIVE Output : EVIL 🎥 I’ve also created a short video explaining this concept with code: YouTube link : https://lnkd.in/eKH2JJwa #Java #Programming #ProblemSolving #Coding #SoftwareDevelopment #Learning #CSE #Developers #LogicBuilding #String

Java isn’t just a programming language — it’s one of the best ways to build a real programming mindset. ☕💻 It teaches you: Logic Problem solving OOP concepts Clean coding basics That’s why Java is still one of the best languages for beginners and future developers. From variables and loops to classes and objects, Java helps you build a strong coding foundation. This is my first post in my coding journey, and I’ll be sharing Java in the simplest way possible. Let’s learn and grow together. 🚀 #Java #Programming #Coding #LearnJava #Developer #100DaysOfCode #TechTwitter #CodeNewbie #JavaDeveloper

🚀 Mastering Java Through LeetCode 🧠 Day 22 of My DSA Journey Today I solved an interesting matrix-based problem that improved my understanding of arrays and comparison logic. 📌 LeetCode Problem Solved Today: 2352 – Equal Row and Column Pairs Problem Statement: Given an n x n matrix, find how many pairs (row, column) are exactly the same. A pair is valid only if both contain the same elements in the same order. 🧠 Key Idea: Compare each row with every column Check element-by-element equality Count all matching pairs 🔍 Example: Input: [[3,2,1], [1,7,6], [2,7,7]] Output: 1 Matching Pair: Row 2 = Column 1 → [2,7,7] ⚙️ Approach: Traverse all rows Build each column dynamically Compare row[i][k] with column[k][j] If all elements match → increment count ⏱️ Time Complexity: O(n³) (Optimized solution using HashMap possible in O(n²)) What I Learned: Matrix traversal techniques Row vs Column comparison logic Importance of nested loops in grid problems 🔥 Consistency is the key! Every day one problem closer to my goal of becoming a Software Engineer #LeetCode #DSA #Java #CodingJourney #100DaysOfCode #SoftwareEngineer #ProblemSolving #Learning #Tech

🚀 From Machine Code to Java — The Evolution of Simplicity Every line of code we write today stands on decades of innovation. From raw binary instructions to powerful, human-friendly languages — the journey of programming is nothing short of revolutionary. 💡 What fascinates me the most: C was built close to hardware C++ introduced Object-Oriented thinking Java made development simpler, safer, and platform-independent 👉 It’s not just evolution… it’s continuous problem-solving. As developers, we often focus on writing code — but real growth starts when we understand the foundation behind it. 🧠 Key takeaway: The best developers don’t just use technology — they understand how it evolved. Currently diving deep into DSA & Java Full Stack, building not just skills, but strong fundamentals. #Java #DSA #Programming #DeveloperJourney #Tech #Learning #SoftwareDevelopment #GrowthMindset

Most people think coding is about writing logic. But it's something deeper… It’s about thinking clearly when things don’t work. I spent hours debugging a small issue, not because it was hard, but because my thinking was messy. The moment I slowed down, broke the problem and questioned every assumption… The solution appeared in minutes💡 Good developers don’t just code fast. They think better. And that’s what I’m working on every single day. #SoftwareDevelopment #CodingJourney #ProblemSolving #Java #Learning

👋 Hello LinkedIn Network! Ever looked at your code and thought, “Oh no, it’s a total mess!” 😅 Don’t worry, it happens to everyone.Want to write cleaner, more maintainable Java code? Understanding the SOLID principles is a game-changer. Here's a quick cheat sheet: 🔹 S — Single Responsibility Principle One class → one responsibility 🔹 O — Open/Closed Principle Extend behavior without modifying existing code 🔹 L — Liskov Substitution Principle Child classes must behave like parent 🔹 I — Interface Segregation Principle Use small, specific interfaces 🔹 D — Dependency Inversion Principle Depend on interfaces, not concrete classes 💡 Applying these principles helps you build flexible systems that are easier to test, debug, and scale. 🚀 Try using SOLID in your next project and notice the difference! #Java #CleanCode #SOLIDPrinciples #SoftwareEngineering #Programming #Developers

Turning concepts into confidence 💻✨ Recently, I focused on strengthening my core understanding of Java fundamentals — because a strong foundation is what builds great developers. 📌 Topics I explored: ✔ Data Types (Primitive & Non-Primitive) ✔ Type Casting (Implicit & Explicit) ✔ Wrapper Classes ✔ Integer to Binary Conversion ✔ String Handling Basics While these may seem like basic concepts, they play a crucial role in writing efficient, error-free, and optimized programs. Understanding how data is stored, converted, and processed gives a whole new perspective on problem-solving. What I realized is — coding is not just about writing syntax, it’s about understanding the logic behind every step. The more clarity we build in fundamentals, the easier it becomes to tackle complex problems later. Consistency is the key 🔑 Learning a little every day is helping me grow step by step in my developer journey. Looking forward to diving deeper into advanced Java concepts and building real-world applications 🚀 #Java #Programming #DeveloperJourney #Learning #Coding #TechSkills #StudentLife #Consistency #Growth #GQT

Sum of the Array in Java | Easy Logic + Coding 💡 Strong fundamentals are the key to mastering programming. This example shows how to find the sum of array elements using simple logic: • Start with an array of numbers • Initialize a sum variable to 0 • Traverse the array using a loop • Add each element to the sum • Print the final result Practicing these basic problems helps build strong logical thinking and coding confidence. 📊 Example Input : [1, 2, 3, 4] Output : 10 🎥 I’ve also created a short video explaining this concept with code: YouTube link : https://lnkd.in/g9SJ3hvJ #Java #Programming #ProblemSolving #Coding #SoftwareDevelopment #Learning #CSE #Developers #LogicBuilding #Arrays

🚀 Just solved LeetCode's Palindrome Number problem in Java — and all 11,511 test cases passed! ✅ Here's what I learned building a clean, string-based solution: 💡 The Approach: → Convert the integer to a string → Reverse it character by character → Compare the original vs reversed string Simple? Yes. But the real win is in the edge case — returning false immediately for negative numbers. That's clean defensive programming. 🧵 Key Takeaway: You don't always need complex math. Sometimes the most readable solution is the best solution — and readability is what makes code maintainable in production. ⚡ Runtime: 16ms | Memory: 46.62MB Not the fastest (beats 5.61%), but it's clear, correct, and gets the job done. I'm challenging myself to solve problems daily and document my thinking. Consistency > perfection. If you're on a similar DSA journey, let's connect!
