哦,不!你不小心把一个长篇文章中的空格、标点都删掉了,并且大写也弄成了小写。像句子"I reset the computer. It still didn’t boot!"已经变成了"iresetthecomputeritstilldidntboot"。在处理标点符号和大小写之前,你得先把它断成词语。当然了,你有一本厚厚的词典dictionary,不过,有些词没在词典里。假设文章用sentence表示,设计一个算法,把文章断开,要求未识别的字符最少,返回未识别的字符数。
注意:本题相对原题稍作改动,只需返回未识别的字符数
示例
输入:
dictionary = ["looked","just","like","her","brother"]
sentence = "jesslookedjustliketimherbrother"
输出: 7
解释: 断句后为"jess looked just like tim her brother",共7个未识别字符。
