The Challenge – Reverse Factorials:

Everyone is probably familiar with a factorial. 5 factorial is:

5! -> 5 x 4 x 3 x 2 x 1 = 120


For this challenge reverse it! Write LabVIEW code that tells us if our input number is a factorial or not.


If the number is a factorial it should return 'x!' where x is the factorial number.

E.g. 120 is 5 factorial, return '5!'


If the number is not a factorial it should return 'NONE'


The code should handle input numbers up to 9,223,372,036,854,775,807 – consider your data types!













Close date: Monday 17th July

Please note the competition is only open to LabVIEW users in Europe, Middle East, India and Africa.
