You have a chat log of n messages. You are given two string arrays messages and senders where messages[i] is a message sent by senders[i].
A message is list of words that are separated by a single space with no leading or trailing spaces. The word count of a sender is the total number of words sent by the sender. Note that a sender may send more than one message.
\n\nReturn the sender with the largest word count. If there is more than one sender with the largest word count, return the one with the lexicographically largest name.
\n\nNote:
\n\n"Alice" and "alice" are distinct.\n
Example 1:
\n\n\nInput: messages = ["Hello userTwooo","Hi userThree","Wonderful day Alice","Nice day userThree"], senders = ["Alice","userTwo","userThree","Alice"]\nOutput: "Alice"\nExplanation: Alice sends a total of 2 + 3 = 5 words.\nuserTwo sends a total of 2 words.\nuserThree sends a total of 3 words.\nSince Alice has the largest word count, we return "Alice".\n\n\n
Example 2:
\n\n\nInput: messages = ["How is leetcode for everyone","Leetcode is useful for practice"], senders = ["Bob","Charlie"]\nOutput: "Charlie"\nExplanation: Bob sends a total of 5 words.\nCharlie sends a total of 5 words.\nSince there is a tie for the largest word count, we return the sender with the lexicographically larger name, Charlie.\n\n
\n
Constraints:
\n\nn == messages.length == senders.length1 <= n <= 1041 <= messages[i].length <= 1001 <= senders[i].length <= 10messages[i] consists of uppercase and lowercase English letters and ' '.messages[i] are separated by a single space.messages[i] does not have leading or trailing spaces.senders[i] consists of uppercase and lowercase English letters only.给你一个聊天记录，共包含 n 条信息。给你两个字符串数组 messages 和 senders ，其中 messages[i] 是 senders[i] 发出的一条 信息 。
一条 信息 是若干用单个空格连接的 单词 ，信息开头和结尾不会有多余空格。发件人的 单词计数 是这个发件人总共发出的 单词数 。注意，一个发件人可能会发出多于一条信息。
\n\n请你返回发出单词数 最多 的发件人名字。如果有多个发件人发出最多单词数，请你返回 字典序 最大的名字。
\n\n注意：
\n\n\"Alice\" 和 \"alice\" 是不同的名字。\n\n
示例 1：
\n\n输入：messages = [\"Hello userTwooo\",\"Hi userThree\",\"Wonderful day Alice\",\"Nice day userThree\"], senders = [\"Alice\",\"userTwo\",\"userThree\",\"Alice\"]\n输出：\"Alice\"\n解释：Alice 总共发出了 2 + 3 = 5 个单词。\nuserTwo 发出了 2 个单词。\nuserThree 发出了 3 个单词。\n由于 Alice 发出单词数最多，所以我们返回 \"Alice\" 。\n\n\n
示例 2：
\n\n输入：messages = [\"How is leetcode for everyone\",\"Leetcode is useful for practice\"], senders = [\"Bob\",\"Charlie\"]\n输出：\"Charlie\"\n解释：Bob 总共发出了 5 个单词。\nCharlie 总共发出了 5 个单词。\n由于最多单词数打平，返回字典序最大的名字，也就是 Charlie 。\n\n
\n\n
提示：
\n\nn == messages.length == senders.length1 <= n <= 1041 <= messages[i].length <= 1001 <= senders[i].length <= 10messages[i] 包含大写字母、小写字母和 ' ' 。messages[i] 中所有单词都由 单个空格 隔开。messages[i] 不包含前导和后缀空格。senders[i] 只包含大写英文字母和小写英文字母。\\u7248\\u672c\\uff1a \\u7f16\\u8bd1\\u65f6\\uff0c\\u5c06\\u4f1a\\u91c7\\u7528
