Collatz Conjecture
Easy
0.0% Acceptance
The Collatz Conjecture or 3x+1 problem can be summarized as follows:
Take any positive integer n.
If n is even, divide n by 2 to get n / 2.
If n is odd, multiply n by 3 and add 1 to get 3n + 1.
Repeat the process indefinitely.
The conjecture states that no matter which number you start with, you will always reach 1 eventually.
Given a number n, return the number of steps required to reach 1.
Examples
Starting with n = 12, the steps would be as follows:
- 12
- 6
- 3
- 10
- 5
- 16
- 8
- 4
- 2
- 1
Resulting in 9 steps.
So for input n = 12, the return value would be 9.
