Day 16 – Find the Second Largest Element in an Array (Java & Python) > 💡 Problem: Given an array of integers, find the second largest element. Example: Input → [10, 25, 3, 99, 56, 77] Output → 77 Approach – Single Pass (Optimized O(n)): Initialize two variables:   first = second = -∞ Traverse the array:   If current > first → update second = first, then first = current.   Else if current > second and current != first → update second = current. One traversal, no sorting needed! Your Turn: Can you modify this to find both smallest and second smallest elements?

I'm glad that the annoying term "mashup" has faded since its 2015 peak. https://lnkd.in/eCU-AccU But it might be pointing to a darker truth: that combining two Python programs with different/conflicting dependency lists is harder than it was in Java, because vendoring is not as robust as shading.

Dictionary in Python A dictionary in Python stores data in pairs. One side is the key and the other side is the value. Example: Dict = {1: "Python", 2: "C++", 3: "Java"} ✔ Key 1 → Value Python ✔ Key 2 → Value C++ ✔ Key 3 → Value Java

Lately, I've been playing with Python and noticed how it handles multiple inheritance. honestly, it’s much simpler compared to C#. In C#, we can’t inherit from multiple classes (the compiler just stops us). But in Python, it works smoothly using something called MRO (Method Resolution Order). A small example of the diamond problem Python just figures out the order (D → B → C → A). C# avoids it altogether, no diamond problem, no confusion. 👉 And yes, I know we have interfaces in C#, but they don’t really solve the diamond problem, they just avoid it by not carrying implementation. Two different philosophies. Both make sense. But Python’s flexibility here felt refreshing 😊 #CSharp #Python #Developers #LearningEveryday #OOP

Everyone’s busy writing OOP in Python and Java. I decided to pull off polymorphism in C instead. A short blog , I wrote on it. https://lnkd.in/gjd7Cnpx

Day 10 – Print a Half Pyramid Pattern (Java & Python) > 💡 Problem: Print a half-pyramid of stars (*) based on the number of rows. Example (n = 5): * ** *** **** ***** 🧠 Approach: 1️⃣ Use two nested loops —   Outer loop → for each row   Inner loop → for printing stars in that row 2️⃣ Print a newline after each row. Time Complexity: O(n²) Space Complexity: O(1) Your Turn: Can you modify this to print an inverted pyramid or a right-aligned one?

Built Objectron, a lightweight custom ORM written entirely from scratch in Python. >> Key Features: > Model-to-Table mapping using Python classes > Field Descriptors with schema constraints (primary key, nullable, unique) > Session Management via the Unit of Work pattern > Clean Connection Handling > Database Agnostic through Adapters (currently supports SQLiteDialect) > Dynamic Query Builder with chaining, filters, and sorting Objectron is an open-source ORM built to serve as a learning-friendly reference for understanding ORM internals. Building it from scratch also gave me a much deeper understanding of OOP concepts. Repo link: https://lnkd.in/dDdVg-cb

This week has been about Python in Node.js, modern CSS colour functions, graph queries in DuckDB and an article on LLMs explicitly ignoring ethical constraints. https://lnkd.in/eKmetcJQ

Day 15 – Find the Largest Element in an Array (Java & Python) 💡 Problem: Given an array of integers, find the largest element. Example: Input → [10, 25, 3, 99, 56, 77] Output → 99 🧠 Approach: 1️⃣ Initialize a variable max with the first element. 2️⃣ Traverse the array — If arr[i] > max, update max = arr[i]. 3️⃣ After one full pass, max holds the largest value. Time Complexity: O(n) Space Complexity: O(1) Your Turn: Can you modify this to find both minimum and maximum in a single traversal? (Hint: use two variables 😉) Drop your code below 👇 #CodeWithTanseer #DSA #Java #Python #CodingChallenge #ProblemSolving #Arrays #LogicBuilding #SoftwareEngineer #BackendDeveloper #InterviewPrep

TWIL*: You can write VSCode extensions in Python using my PyScript LTK UI toolkit, which runs in WebAssembly and renders the UI in Python within a WebView (Chromium). Is this cool, or is this super cool? In the screenshot, the tree on the left is generated in TypeScript. The WebView content on the right is done in Python. The two environments can send each other messages, so from the WebView you can read Python files from your workspace, parse them, analyse the AST, and do all kinds of interesting things. *=This Weekend I Learned
