<p>You have a chat log of <code>n</code> messages. You are given two string arrays <code>messages</code> and <code>senders</code> where <code>messages[i]</code> is a <strong>message</strong> sent by <code>senders[i]</code>.</p>
|
|
|
|
<p>A <strong>message</strong> is list of <strong>words</strong> that are separated by a single space with no leading or trailing spaces. The <strong>word count</strong> of a sender is the total number of <strong>words</strong> sent by the sender. Note that a sender may send more than one message.</p>
|
|
|
|
<p>Return <em>the sender with the <strong>largest</strong> word count</em>. If there is more than one sender with the largest word count, return <em>the one with the <strong>lexicographically largest</strong> name</em>.</p>
|
|
|
|
<p><strong>Note:</strong></p>
|
|
|
|
<ul>
|
|
<li>Uppercase letters come before lowercase letters in lexicographical order.</li>
|
|
<li><code>"Alice"</code> and <code>"alice"</code> are distinct.</li>
|
|
</ul>
|
|
|
|
<p> </p>
|
|
<p><strong>Example 1:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> messages = ["Hello userTwooo","Hi userThree","Wonderful day Alice","Nice day userThree"], senders = ["Alice","userTwo","userThree","Alice"]
|
|
<strong>Output:</strong> "Alice"
|
|
<strong>Explanation:</strong> Alice sends a total of 2 + 3 = 5 words.
|
|
userTwo sends a total of 2 words.
|
|
userThree sends a total of 3 words.
|
|
Since Alice has the largest word count, we return "Alice".
|
|
</pre>
|
|
|
|
<p><strong>Example 2:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> messages = ["How is leetcode for everyone","Leetcode is useful for practice"], senders = ["Bob","Charlie"]
|
|
<strong>Output:</strong> "Charlie"
|
|
<strong>Explanation:</strong> Bob sends a total of 5 words.
|
|
Charlie sends a total of 5 words.
|
|
Since there is a tie for the largest word count, we return the sender with the lexicographically larger name, Charlie.</pre>

|
<p> </p>
|
|
<p><strong>Constraints:</strong></p>
|
|
|
|
<ul>
|
|
<li><code>n == messages.length == senders.length</code></li>
|
|
<li><code>1 <= n <= 10<sup>4</sup></code></li>
|
|
<li><code>1 <= messages[i].length <= 100</code></li>
|
|
<li><code>1 <= senders[i].length <= 10</code></li>
|
|
<li><code>messages[i]</code> consists of uppercase and lowercase English letters and <code>' '</code>.</li>
|
|
<li>All the words in <code>messages[i]</code> are separated by <strong>a single space</strong>.</li>
|
|
<li><code>messages[i]</code> does not have leading or trailing spaces.</li>
|
|
<li><code>senders[i]</code> consists of uppercase and lowercase English letters only.</li>
|
|
</ul>
