Collatz Sequence is a sequence named after the German mathematician Lothar Collatz. What is Collatz Sequence? Think of a positive integer "n", if "n" is a even number, then divide it by 2; otherwise multiply it by 3 and then plus 1. Repeat the same calculation until the number is 1. This sequence is called "Collatz Sequence". For example, the Collatz Sequence starting from 13 is: 13, 40, 20, 10, 5, 16, 8, 4, 2, 1. You can type any other positive numbers in this project to try how many steps to take it to 1! Collatz also proposed a conjecture that every Collatz sequence starting from a positive integer "n" will end at 1 eventually. But mathematicians haven't proved or disproved this conjecture yet.
