## Description
<section id='description'> 
Para cualquier N, sea f (N) los últimos cinco dígitos antes de los ceros finales en N !. 
Por ejemplo, 
9! = 362880 entonces f (9) = 36288 
10! = 3628800 entonces f (10) = 36288 
20! = 2432902008176640000 entonces f (20) = 17664 
Encuentre f (1,000,000,000,000)
