Type in an input for N (e.g. 72) and the program will process it. The out list is the output of each computation; every time N is set to nf. The last index of the list will be the final output, given that the program halts. The frac list stores fractions in integer form, being numerators and denominators. Odd numbers are numerators, and even numbers vice versa.
