We’re given an ascending string of integers that represents page numbers.

Write a function <code>get_last_page</code> to return the last page number in the string. If the string of integers is not in the correct page order, return the last number in order.

Example 1:

Input:

<pre tabindex="0" class="chroma"><code>input = &#39;12345&#39;
</code></pre>

Output:

<pre tabindex="0" class="chroma"><code>output = 5
</code></pre>

Example 2:

Input:

<pre tabindex="0" class="chroma"><code>input = &#39;12345678910111213&#39;
</code></pre>

Output:

<pre tabindex="0" class="chroma"><code>output = 13
</code></pre>

Example 3:

Input:

<pre tabindex="0" class="chroma"><code>input = &#39;1235678&#39;
</code></pre>

Output:

<pre tabindex="0" class="chroma"><code>output = 3
</code></pre>
