"content": "<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>\n\n<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>\n\n<p>Return <em>the sender with the <strong>largest</strong> word count</em>.
