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>

Last Page Number

Data Structures & Algorithms

You are given two sentences as <code>strings</code>. Create a function that returns a list of all words that are not in both sentences.

You can assume that the sentences have no punctuation marks, extra tabs, or spaces.

Note: The strings <code>&#34;Game&#34;</code> and <code>&#34;game&#34;</code> should be considered the same word. Because of this, make sure all the strings in the list you output are in lowercase.

Example:

Input:

<pre tabindex="0" class="chroma"><code>string1 = &#34;I want to eat fish today with my friends&#34;
string2 = &#34;All I want is to eat fish today with my friends&#34;
</code></pre>

Output:

<pre tabindex="0" class="chroma"><code>def mismatched_words(string1,string2) -&gt; [&#34;all&#34;,&#34;is&#34;]
</code></pre>

Let’s say you’re working on keyword bidding optimization. You’re given a dataset with two columns. One column contains the keywords that are being bid against, and the other column contains the price that’s being paid for those keywords.

Given this dataset, how would you build a model to bid on a new unseen keyword?
