The Collatz Ride

The strangest ride in mathematics: even numbers get halved, odd numbers become 3n+1. Every number ever tested eventually crashes into 1 — nobody on Earth has proven they all must! 🎢

You get a starting n. Print how many steps the ride takes to reach 1.

Example:

Input: n = 6 Output: 8

The ride goes 6 → 3 → 10 → 5 → 16 → 8 → 4 → 2 → 1 — that's 8 steps to reach 1.
