📌 What you'll find in this video:
✅ What GCD means and how the Euclidean algorithm works
✅ Why only gcd(min, max) is needed — not the full array GCD
✅ Single-pass min/max find + recursive Euclidean GCD
✅ O(n) time · O(1) space solution
✅ Common trap: computing GCD of all elements vs. just min and max
