The collatz conjecture

Question

I was asked to come up wth pseudocode to demonstrate the above mentioned algorithm. Bacically you pick a positive number
and if its odd you triple it and add one, else you half it. I did all that but now I have to show how many items are in the series and what is the largest one. I also can stop the series when 4 is computed as it leads us to the ground state. meaning it repeats the numbers 421421...(and i include this explanation only to be clear, i dnt want to assume that everyone knows it as I also found out about it in class today)
Thanks in advance

Here's my attempt at generating a Collatz sequence for a random number between 1 and 1000. I haven't bothered with the ground state value of 4 which only complicates matters: using System; class Collatz { static Random rand = new Random(); static void Main() { int n = rand.Next(1 1001); GenerateSequence(n); Console.ReadKey(); } static void GenerateSequence(int n) { if (n int max = n; int count = 1; Console.Clear(); Console.WriteLine({0} (starting number in Collatz sequence) n); while (n > 1) { if (n % 2 == 0) { n = n /2; } else { n = 3 * n + 1; } count++; if (n > max) max = n; Console.WriteLine(n); } Console.WriteLine(
There are {0} items(s) in the sequence count); Console.WriteLine(The largest number in the sequence is {0} max); } }
