Datastructure Problem and Solution

Section 1

1. Fizz Buzz problem
2. Palimdrome number
3. Number of trailing zeros in a factorial of a number
   Solution is to find the count of 5 which are available in the factorial
   Example: !10 = 1 * 2 * 3 * 4 * 5 * 6 * 7 * 8 * 9 * 10
   which is further rewritten as !10 = 1 * 2 * 3 * 4 * 5 * 6 * 7 * 8 * 9 * 2 * 5
   Answer: Number trailing zero = 2
4. Power(x, n)
