keep first m nodes and delete next n nodes
Given a singly link list, you have to keep first M nodes and then delete next N nodes, again keep M nodes and delete next N nodes and so on.Write a algo for this.
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
