The Collatz conjecture is a conjecture in mathematics named after Lothar Collatz. It can be summarized as follows. Take any positive integer n. If n is even, divide it by 2 to get n / 2. If n is odd, multiply it by 3 and add 1 to obtain 3n + 1. [More on Wikipedia ](https://en.wikipedia.org/wiki/Collatz_conjecture)
