Instructions
Write a program that takes a positive int and displays its prime factors on the standard output, followed by a newline.
-
Factors must be displayed in ascending order and separated by
*, so that the expression in the output gives the right result. -
If the number of parameters is not 1, simply display a newline.
-
The input, when there's one, will be valid.
