| * The 3n + 1 Problem | |
| *Consider the following algorithm to generate a sequence of numbers. Start with an | |
| *integer n. If n is even, divide by 2. If n is odd, multiply by 3 and add 1. Repeat this | |
| *process with the new value of n, terminating when n = 1. For example, the following | |
| *sequence of numbers will be generated for n = 22: | |
| *22 11 34 17 52 26 13 40 20 10 5 16 8 4 2 1 | |
| *It is conjectured (but not yet proven) that this algorithm will terminate at n = 1 for | |
| *every integer n. Still, the conjecture holds for all integers up to at least 1, 000, 000. | |
| *For an input n, the cycle-length of n is the number of numbers generated up to and |
