Python program to count number of trailing zeros in Factorial of number N

Web2 jan. 2024 · Factorial: The factorial of a number, n denoted by n! is the product n* (n-1)* (n-2)...*1 . For example, 5! = 5*4*3*2*1 = 120. Trailing zeros: The trailing zeros of a number is the number of zeros at the end of a number. For example, the number 567100 has two trailing zeros. WebIn this number, the number of trailing zeros is 0, which is wrong. First of all, the factorial of any number can never be negative. Also, the value of 50! = 30414093202413378043612608166064768844377641568960512000000000000, and the number of trailing zeros in this number is 12, and the above program fails in both … WebTrailing Zeros in Factorial - Problem Description Given an integer A, return the number of trailing zeroes in A!.

"WebOne simple approach to count trailing zeros is first find factorial of number and then count the zeros in the factorial one by one. It is fine for smaller number like 10. 10! = 3628800 So, trailing zeros = 2 But what about big numbers like 100. The factorial of 100 has 24 zeros in the end and almost 160 digits.
