(20/100) AVOID using namespace std; ⚠️

Think using namespace std; just slows down your C++ code? ❌ It's not!

The real, insidious danger is name collision and global scope pollution that turns your codebase into unreadable spaghetti!

I'll show you the exact conflict (like clashing with std::count) and the one simple rule to keep your code clean, prevent ambiguity, and avoid a maintainability nightmare.

💡 The Rule: Always explicitly qualify with std:: or use specific using std:: declarations. Never globally pollute!
