Given an integer n, write a function that returns count of trailing zeroes in n!. Examples: Input: n = 5 Output: 1 Factorial of 5 is 20 which has one trailing 0. Input: n = 20 Output: 4 Factorial of 20 is 2432902008176640000 which has 4 trailing zeroes. Input: n = 100 Output: 24
potential bug in first statement...
ReplyDeleteif ( x == 0 ) // if we forget and make it single =, it becomes x = 0, and the bug is severe that cant be found so easily unless we have eagle eyes :)
so second statement is better.
@B Ramesh yeah very true and if we make it single = in second statement it will give error.(invalid lvalue in assisgment).
