Description

Given an infinite number of quarters (25 cents), dimes (10 cents), nickels (5 cents), and pennies (1 cent), write code to calculate the number of ways of representing n cents. (The result may be large, so you should return it modulo 1000000007)

Example1:


 Input: n = 5

 Output: 2

 Explanation: There are two ways:

5=5

5=1+1+1+1+1

Example2:


 Input: n = 10

 Output: 4

 Explanation: There are four ways:

10=10

10=5+5

10=5+1+1+1+1+1

10=1+1+1+1+1+1+1+1+1+1

Notes:

You can assume:

  • 0 <= n <= 1000000
