+Weird algorithm
+Consider an algorithm that takes as input a positive integer n. If n is even, the algorithm divides it by two, and if n is odd, the algorithm multiplies it by three and adds one. The algorithm repeats this, until n is one. For example, the sequence for n=3 is as follows:
+3?10?5?16?8?4?2?1
+
+Your task is to simulate the execution of the algorithm for a given value of n.
