Let’s say there are many vehicles on a long road. At each mile along the road, a checkpoint indicates the length traveled across the road.

You are given a list called <code>vehicles</code> which indicates the number of vehicles between each checkpoint. For example, the list <code>[7,4,3]</code> would mean that there are seven vehicles before the first checkpoint, four vehicles between the first and second checkpoints, and three vehicles between the second and third checkpoints.

Write a function <code>range_vehicles</code> that will give the number of vehicles between the <code>start</code> and <code>end</code> checkpoints.

Note: <code>start</code> may be <code>0</code>

Example:

Input:

<pre tabindex="0" class="chroma"><code>vehicles = [5, 6, 4, 2, 1]
start = 1
end = 3
</code></pre>

Output:

<pre tabindex="0" class="chroma"><code>range_vehicles(vehicles,start,end) -&gt; 10
</code></pre>

Counting Vehicles

You work at a freight shipping company with a large fleet of trucks. These trucks are based around the nation, with a mix of Mercedes and BMW models represented. The location of each truck that your company owns is stored as <code>(x,y)</code> coordinates in your database.

Given a list of locations that your trucks are stored at, return the top location <code>(x,y)</code> for each model of truck (Mercedes or BMW).

You can assume that there is one location with the most model of a truck, e.g. there will not be any locations that are tied for most BMWs stored.

Example:

Input:

<pre tabindex="0" class="chroma"><code>truck_locations = [{
 &#34;model&#34; : &#34;BMW&#34;,
 &#34;location&#34; : (1,2)
 },
 {
 &#34;model&#34; : &#34;Mercedes&#34;,
 &#34;location&#34; : (2,3)
 },
 {
 &#34;model&#34; : &#34;Mercedes&#34;,
 &#34;location&#34; : (2,2)
 },
 {
 &#34;model&#34; : &#34;Mercedes&#34;,
 &#34;location&#34; : (2,3)
 },
 {
 &#34;model&#34; : &#34;BMW&#34;,
 &#34;location&#34; = (1,2)
 },
 {
 &#34;model&#34; : &#34;BMW&#34;,
 &#34;location&#34; : (3,3)
 }
 ]
</code></pre>

Output:

<pre tabindex="0" class="chroma"><code>def truck_frequent_location(truck_locations) -&gt; { 
 &#34;Mercedes&#34; : (2,3), 
 &#34;BMW&#34; : (1,2) 
 }
}
</code></pre>

Explanation:

Mercedes repeated two times at location <code>(2,3)</code> and one time at the location <code>(2,2)</code>, so <code>(2,3)</code> is our most stored Mercedes location.

BMW repeated two times at location <code>(1,2)</code> and one time at the location <code>(3,3)</code>, so <code>(1,2)</code> is our most stored BMW location.

Given a list of locations that your trucks are stored at, return the top location for each model of truck (Mercedes or BMW).
