### Test your Programming Skill : P-2

Our today's Programming Problem is quite easier . It uses your Basic mathematics skill of School level But Really This Problem Test your skills .

and you have to find out number of Zero's at end of 15 ! = 3

as

**You Have to Find Number of Zeros at end of factorial of a number without using real factorisation****example : let No be 15 then 15 ! (15 factorial ) =1*2*3* ..........*13*14*15**and you have to find out number of Zero's at end of 15 ! = 3

as

**15!=1307674368000 .****I Gave you some results to check your Program output . So hurry Up .**
