Day 2/100 – #100DaysOfCode Problem Solved: Merge Sorted Array (Python) Instead of using extra space, I applied the three-pointer technique to merge arrays in-place. Pointers Used: i → Last valid element of nums1 j → Last element of nums2 k → Last position of merged array By filling the array from the back, we avoid overwriting important values. Efficient. Clean. Interview-ready. 🚀 #PythonDeveloper #DataStructures #TechInterviewPrep

#Day - 32 LeetCode #334 – Increasing Triplet Subsequence (Medium) In this problem, the goal was to determine whether an array contains an increasing triplet subsequence in O(n) time and O(1) space complexity. 🔹 Approach Used: Maintained two variables (first and second) initialized to infinity. Iterated through the array once. Updated first and second dynamically. Returned True when a valid third element was found. This problem strengthened my understanding of: ✅ Greedy algorithms ✅ Optimized space complexity ✅ Efficient single-pass solutions ✅ Logical thinking for edge cases Under the Guidance of : Rudra Sravan kumar #LeetCode #ProblemSolving #Python #DataStructures #Algorithms #CodingJourney #SoftwareDeveloper

I'm wrapping up 𝐝𝐲𝐧𝐚𝐦𝐢𝐜-𝐝𝐞𝐬, a new Python package extending 𝘚𝘪𝘮𝘗𝘺 to build live 𝐃𝐢𝐠𝐢𝐭𝐚𝐥 𝐓𝐰𝐢𝐧𝐬. 🚀 It turns static simulations into real-time, event-driven models capable of updating parameters on the fly and streaming live telemetry. I'll be publishing it to PyPI soon! Here is a sneak peek at the control dashboard in action. 👇 Code and repo dropping shortly, fingers crossed! #DigitalTwin #SimPy #Python #DES #Simulation #Kafka #Engineering

This week, Palomino has released a SARIMAX forecasting sandbox demonstration. A demo dataset and a walkthrough on using SARIMAX on the platform are available at https://palominoai.com. Our SARIMAX implementation is a no-code forecasting solution. It brings powerful, AI assisted forecasting capabilities without the hassle of setting up a Python, R or Matlab environment.

🔍 Longest Substring with Exactly K Distinct Characters Solved using the Sliding Window technique to track character frequency and maintain a window with exactly K distinct characters. ⏱ Time: O(n) | Space: O(k) Example: s = "aabacbebebe", k = 3 → 7 #geekstreak60 #npci #Python #DSA #SlidingWindow #CodingPractice #ProblemSolving #Tech

🔥 Day 30 of #100DaysOfCode 📌 LeetCode 26 – Remove Duplicates from Sorted Array Today’s problem focused on in-place array manipulation and strengthening the two-pointer technique. 🧠 Problem Summary Given a sorted array, remove duplicates such that each unique element appears only once. Return the count of unique elements (k). Important: Do it in-place with O(1) extra space. 💡 Key Insight Because the array is already sorted, duplicates are always adjacent. So instead of checking all elements repeatedly: 👉 Compare current element with previous one. 👉 If different → place it at the next unique index. This is where the Two Pointer Approach shines: Pointer i → traverses array Pointer k → tracks position of next unique element 📊 Complexity ⏱ Time: O(n) 📦 Space: O(1) Consistency > Motivation 30 Days Done. Still going strong 💪 #Day30 #LeetCode #DSA #100DaysOfCode #Python #CodingJourney

Few think about memory. In high-scale systems, memory efficiency matters more than micro-speed gains. Small habits that scale: Use generators instead of large lists Avoid unnecessary object copies Understand mutable vs immutable types Be careful with default mutable arguments Efficient memory usage = predictable systems. That’s engineering maturity. #Python #Performance #ScalableSystems #SoftwareEngineering
