<p>A website domain <code>"discuss.leetcode.com"</code> consists of various subdomains. At the top level, we have <code>"com"</code>, at the next level, we have <code>"leetcode.com"</code> and at the lowest level, <code>"discuss.leetcode.com"</code>. When we visit a domain like <code>"discuss.leetcode.com"</code>, we will also visit the parent domains <code>"leetcode.com"</code> and <code>"com"</code> implicitly.</p>
<p>A <strong>count-paired domain</strong> is a domain that has one of the two formats <code>"rep d1.d2.d3"</code> or <code>"rep d1.d2"</code> where <code>rep</code> is the number of visits to the domain and <code>d1.d2.d3</code> is the domain itself.</p>
<ul>
<li>For example, <code>"9001 discuss.leetcode.com"</code> is a <strong>count-paired domain</strong> that indicates that <code>discuss.leetcode.com</code> was visited <code>9001</code> times.</li>
</ul>
<p>Given an array of <strong>count-paired domains</strong><code>cpdomains</code>, return <em>an array of the <strong>count-paired domains</strong> of each subdomain in the input</em>. You may return the answer in <strong>any order</strong>.</p>
<strong>Explanation:</strong> We will visit "google.mail.com" 900 times, "yahoo.com" 50 times, "intel.mail.com" once and "wiki.org" 5 times.
For the subdomains, we will visit "mail.com" 900 + 1 = 901 times, "com" 900 + 50 + 1 = 951 times, and "org" 5 times.
<li><code>cpdomain[i]</code> follows either the <code>"rep<sub>i</sub> d1<sub>i</sub>.d2<sub>i</sub>.d3<sub>i</sub>"</code> format or the <code>"rep<sub>i</sub> d1<sub>i</sub>.d2<sub>i</sub>"</code> format.</li>
<li><code>rep<sub>i</sub></code> is an integer in the range <code>[1, 10<sup>4</sup>]</code>.</li>
<li><code>d1<sub>i</sub></code>, <code>d2<sub>i</sub></code>, and <code>d3<sub>i</sub></code> consist of lowercase English letters.</li>
