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.
