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?

Keyword Bidding

You are given two rectangles <code>a</code> and <code>b</code> each defined by four ordered pairs denoting their corners on the <code>x</code>, <code>y</code> plane. Write a function <code>rectangle_overlap</code> to determine whether or not they overlap. Return <code>True</code> if so, and <code>False</code> otherwise.

Note: If the two rectangles border one another, or share a corner like two diagonally adjacent positions on a chessboard, they are said to overlap.

Note: The lists of ordered pairs are in no particular order. The first entry in list <code>a</code> could be the top left corner while the first in list <code>b</code> is the bottom right.

Example:

Input:

<pre tabindex="0" class="chroma"><code>
a = [(-3,5), (-3,2),(0,5),(0,2)]
b = [(-1,4), (3,4), (3,1), (-1,1)]
</code></pre>

Output:

<pre tabindex="0" class="chroma"><code>def rectangle_overlap(a, b) -&gt; True
</code></pre>

As point <code>(0,2)</code> is fully contained in rectangle <code>b</code> and point <code>(-1,4)</code> is fully contained in a rectangle <code>a</code>.

Write a function to determine whether or not two rectangles overlap.

Rectangle Overlap

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>
