99% of beginners think 1 is prime.
It's NOT.
Here's the Java trick that solves HackerRank Prime Checker without overloading:
→ Use int... nums (varargs)
→ Loop only to √n (i*i ≤ n)
→ One static import kills the compile bug

#LeetCode #DynamicProgramming #Golang #100DaysOfCod
As a coder, the hardest bug isn’t in the code.
It’s distraction.
New frameworks.
New AI tools
New tutorials.
You start everything and finish nothing.
Now I focus on one thing: write code daily and ship small
That’s how real builders grow

📚 Today in JavaScript:
🧠 Call Stack – how JS executes code
⬆️ Hoisting – variables & functions move up
🌍 Global vs 🏠 Local Scope – scope clarity
Learning slowly but staying consistent 💪

Day 53! 🐍
Big shift today: moved into Asynchronous Programming and the core pillars of OOP (Classes, Inheritance, and Polymorphism).
I'm learning how to make my code reusable, flexible, and efficient. No more messy scripts it’s time for proper software design. 🏗️🚀

Day 26 — Thinking differently
List comprehension changed how I approach problems today.
The NATO Alphabet project made the lesson stick.
Clean logic feels good.
