Siemens Interview Questions, Process, and Tips

Q1. How many zeros are there in the factorial of n?
Ans. 
The number of zeros in the factorial of n depends on the number of factors of 5 in n!
• Count the number of factors of 5 in n! to determine the number of zeros

• For example, in 10! = 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1, there is one factor of 5, so there is one zero at the end
