Dynamic Programming ⚙️ Result: ✔️ Accepted ✔️ Optimized approach ✔️ Deeper understanding of problem structuring 💡 Takeaway: Strong solutions come from breaking problems into smaller, reusable pieces. #LeetCode #Algorithms #DataStructures #ProblemSolving #CodingJourney

A lot of real-world work isn’t complex… it’s repetitive. And that’s exactly what I tried to solve today 👇 🚀 Day 24 of #100DaysOfCode I built a Mail Merge automation tool using Python that generates personalized letters automatically. 🔧 What this project shows: ✔ Working with file systems and structured data ✔ Applying template-based logic ✔ Automating repetitive workflows efficiently 💡 Key insight: Even simple scripts can create meaningful impact when applied to the right problem. This project took less than 30 lines of code — but replaces hours of manual effort. As a Master of Computer Science student at the University of Adelaide, I’m focused on building solutions that are practical, efficient, and scalable. 📂 GitHub: https://lnkd.in/gP2fVATR Always looking to improve and build better systems. #Python #Automation #SoftwareEngineering #DataScience #MachineLearning #AI #100DaysOfCode #CodingJourney #TechSkills #Programming #Developers #Adelaide #Australia #LearnToCode #FutureOfWork

🚀  Day 29 LeetCode Problem Solved: Longest Consecutive Sequence (128) Today I solved an interesting Data Structures & Algorithms problem on LeetCode. 💻 🔹 Problem: Given an unsorted array of integers, find the length of the longest consecutive elements sequence in O(n) time complexity. 🔹 Example: Input: [100, 4, 200, 1, 3, 2] Output: 4 👉 The longest consecutive sequence is [1,2,3,4]. 🔹 Approach: Instead of sorting the array (which takes O(n log n)), I used a HashSet to achieve O(n) time complexity. ✔ Store all numbers in a HashSet ✔ Identify the start of a sequence (num - 1 not present in the set) ✔ Expand the sequence forward (num + 1, num + 2...) ✔ Track the maximum length 🔹 Complexity: ⏱ Time Complexity: O(n) 📦 Space Complexity: O(n) 💡 Key Learning: Using HashSet efficiently can help optimize problems that involve searching and sequence detection. Excited to keep learning and improving problem-solving skills! 🚀 #leetcode #coding #java #datastructures #algorithms #softwaredeveloper #programming #codingjourney

Day 68 on LeetCode Guess Number Higher or Lower 🎯✅ Today’s problem reinforced the power of Binary Search on an answer space. 🔹 Approach Used in My Solution The goal was to identify a hidden number using the provided guess() API. Key idea in the solution: • Apply binary search between 1 and n • Pick mid and call guess(mid) • Based on the response:   – 0 → correct number found   – -1 → guessed number is too high → move left   – 1 → guessed number is too low → move right • Continue narrowing the search space until the number is found This is a perfect example of searching efficiently using feedback. ⚡ Complexity: • Time Complexity: O(log n) • Space Complexity: O(1) 💡 Key Takeaways: • Strengthened understanding of binary search with external APIs • Learned how to adjust search space based on feedback • Reinforced the concept of searching on answer space 🔥 Another solid step in mastering binary search patterns! #LeetCode #DSA #Algorithms #DataStructures #BinarySearch #DivideAndConquer #ProblemSolving #Coding #Programming #Cpp #STL #SoftwareEngineering #ComputerScience #CodingPractice #DeveloperLife #TechJourney #CodingDaily #100DaysOfCode #BuildInPublic #AlgorithmPractice #CodingSkills #Developers #TechCommunity #SoftwareDeveloper #EngineeringJourney

Day 7 of #100DaysOfCode – Strengthening Logic, One Step at a Time! This week is really showing me one thing clearly… 👉 Programming is not about syntax, it’s about thinking clearly 🧠💻 Today I worked on 10 new problems that improved my understanding of numbers, patterns, and validations ✨ What I explored today (Programs 76–85): 🔹 Mathematical thinking ✔️ Perfect square & cube ✔️ Sum of squares & cubes ✔️ Composite numbers & factor counting ✔️ Largest prime factor 🔹 Real-world logic ✔️ Strong password validation ✔️ Checking numeric-only strings 🔹 Advanced problem solving ✔️ GCD for multiple numbers 💡 Key Learning: Small problems are not “basic”… They are the building blocks of strong logic The more I practice, the more I notice: 👉 My thinking is getting faster 👉 My debugging is getting sharper 🔥 Growth is happening silently… but consistently 💬 No rush, no shortcuts — just daily improvement Global Quest Technologies Special thanks to Global Quest Technologies (GQT) for providing guidance and learning support throughout this journey ✨ #100DaysOfCode #Day7 #Python #PythonProgramming #CodingJourney #ProblemSolving #LearnPython #DeveloperMindset #TechSkills #SoftwareDevelopment #Consistency #GrowthMindset #FutureDeveloper #GlobalQuestTechnologies #GQT

🔍 Solved: Search in a 2D Matrix II (LeetCode 240) Today I worked on an interesting problem that looks simple at first but really tests your understanding of matrix properties. Instead of going with brute force or applying binary search on each row, I used the elimination approach to optimize the search. 💡 Key Insight: The matrix is sorted both row-wise and column-wise. So, starting from the bottom-left corner, we can eliminate either: 1. an entire row (if current element > target), or 2. an entire column (if current element < target) This reduces the search space efficiently at every step. ⚡ Approach Highlights: 1. Start from bottom-left 2. Move up if the value is too large 3. Move right if the value is too small ⏱️ Time Complexity: O(m + n) 📦 Space Complexity: O(1) This approach is much more efficient than checking every element and is a great example of how recognizing patterns in sorted data structures can lead to optimal solutions. #DataStructures #Algorithms #DSA #ProblemSolving #CodingInterview #LeetCode #LeetCodeDaily #CodingPractice #SoftwareEngineering #Programming #Coding #Developer #Tech #ComputerScience #CodeNewbie #Cpp #LearningInPublic #100DaysOfCode #CodeEveryday #KeepLearning #TechJourney #SelfImprovement

Leveling Up with Functions Focus: Functions, Scope, and Efficiency Day 8(04-04-2026): Today was the day I stopped repeating myself! I dove into Functions, and it’s a total game-changer for writing clean code. Instead of writing the same logic over and over, I can now "wrap" it into a function and call it whenever I need it. It’s all about working smarter, not harder. Key concepts I tackled: Parameters vs. Arguments: Understanding the difference between what a function expects and what I actually give it. The Return Statement: Learning how to get a result back from a function so I can use it elsewhere. Variable Scope: This one was tricky! Understanding why a variable created inside a function "disappears" once the function is done (Global vs. Local). In-built Libraries: Starting to explore the massive world of pre-written tools Python offers. It feels like I’m finally moving from writing "scripts" to building "systems." 🏗️ #PythonFunctions #CleanCode #Day8 #TechSkills #CodingLogic
