discountPrices

A sentence is a string of single-space separated words where each word can contain digits, lowercase letters, and the dollar sign <code>&#39;$&#39;</code>. A word represents a price if it is a sequence of digits preceded by a dollar sign.

<ul>
	<li>For example, <code>&quot;$100&quot;</code>, <code>&quot;$23&quot;</code>, and <code>&quot;$6&quot;</code> represent prices while <code>&quot;100&quot;</code>, <code>&quot;$&quot;</code>, and <code>&quot;$1e5&quot;</code> do not.</li>
</ul>

You are given a string <code>sentence</code> representing a sentence and an integer <code>discount</code>. For each word representing a price, apply a discount of <code>discount%</code> on the price and update the word in the sentence. All updated prices should be represented with exactly two decimal places.

Return a string representing the modified sentence.

Note that all prices will contain at most <code>10</code> digits.

&nbsp;
Example 1:

<pre>
Input: sentence = &quot;there are $1 $2 and 5$ candies in the shop&quot;, discount = 50
Output: &quot;there are $0.50 $1.00 and 5$ candies in the shop&quot;
Explanation: 
The words which represent prices are &quot;$1&quot; and &quot;$2&quot;. 
- A 50% discount on &quot;$1&quot; yields &quot;$0.50&quot;, so &quot;$1&quot; is replaced by &quot;$0.50&quot;.
- A 50% discount on &quot;$2&quot; yields &quot;$1&quot;. Since we need to have exactly 2 decimal places after a price, we replace &quot;$2&quot; with &quot;$1.00&quot;.
</pre>

Example 2:

<pre>
Input: sentence = &quot;1 2 $3 4 $5 $6 7 8$ $9 $10$&quot;, discount = 100
Output: &quot;1 2 $0.00 4 $0.00 $0.00 7 8$ $0.00 $10$&quot;
Explanation: 
Applying a 100% discount on any price will result in 0.
The words representing prices are &quot;$3&quot;, &quot;$5&quot;, &quot;$6&quot;, and &quot;$9&quot;.
Each of them is replaced by &quot;$0.00&quot;.
</pre>

&nbsp;
