The Syracuse sequence for an integer is defined as follows: For any integer n less than 1, it is an empty sequence. For n = 1, the sequence is simply 1. For any integer n greater than 1, we use the formula

10,5,16,8,4,2,1.

(n/2 if n is even, 3n+1 if n is odd.

syr(n) = Apply the function syr repeatedly until you reach 1. For example, the Syracuse sequence

for 10 is

Write a function syracuse which takes an integer as an input and returns a string repre- senting its Syracuse sequence.
