Complete the function matchHTML which is to check if a some HTML is properly closed. The function will take in an array of words and html tags. So the HTML code <p>Hello world</p> will be sent to the function as an array like below:

['<p>','Hello','world','</p>']

For now, we only support <h1>, <p> and <ul> and <li>. The function returns true if all tags are properly closed, false if otherwise.

The following HTML is considered to be properly closed:

<h1>Hello</h1>
<p>Welcome!</p>

For each opening html tag, there is a corresponding closed one.

The example below is not properly closed:

<h1>Hello<p>Abc</h1></p>

The closing </h1> tag comes before the closing </p> tag.

Another example of improperly closed tags (the <ul> is not properly closed):

<ul>
 <li>Hi</li>
 <li>Hello</li>

One last case of improperly closed tags:

<ul>
 <li>Hi
 <li>Hello</li>
</ul>
