The Collatz conjecture is a conjecture in mathematics that concerns a sequence defined as follows:

* Start with any positive integer n.

* Then each term is obtained from the previous term as follows:

* if the previous term is even, the next term is one half the previous term.

* If the previous term is odd, the next term is 3 times the previous term plus 1.

The conjecture is that no matter what value of n, the sequence will always reach 1.
