题目描述

在遥远的星际联盟学院里，小珅同学正在参加一场至关重要的“跨物种语言学”研讨会。在这个时代，人类与各种异形生物之间的交流日益频繁，语言成为了连接不同文明的关键桥梁。

“小泽，今天的会议记录员请假了，我们需要你帮忙写一个程序，”小珅老师指着全息屏幕上密密麻麻的外星通讯记录说道，“这些记录包含了星舰舰长的勇敢宣言、机械智能的冷冰冰指令，甚至是其他种族的外星语言。每一句话都饱含着重要的战术信息或外交密约。”

小珅老师提出了具体的需求：“请你编写一个程序，能够自动扫描这些通讯记录，找出每一句话中最长的单词。如果一个句子中包含多个长度相同的‘最长单词’，请优先输出第一个出现的。”

小泽推了推眼镜，脑海中浮现出复杂的分词逻辑和字符串遍历算法。现在，请你帮助小泽完成这个艰巨的任务，让星际联盟的沟通更加顺畅！
