<p>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.&nbsp;(The result may be large, so you should return it modulo 1000000007)</p>

<p><strong>Example1:</strong></p>

<pre>
<strong> Input</strong>: n = 5
<strong> Output</strong>: 2
<strong> Explanation</strong>: There are two ways:
5=5
5=1+1+1+1+1
</pre>

<p><strong>Example2:</strong></p>

<pre>
<strong> Input</strong>: n = 10
<strong> Output</strong>: 4
<strong> Explanation</strong>: 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
</pre>

<p><strong>Notes: </strong></p>

<p>You can assume:</p>

<ul>
	<li>0 &lt;= n&nbsp;&lt;= 1000000</li>
</ul>
