【问题描述】:
高级
我正在尝试折叠句子列表中的常见子字符串,并仅显示它们不同的区域。所以拿这个:
Please don't kick any of the cats
Please do kick any of the cats
Please don't kick any of the dogs
Please do kick any of the dogs
Please don't kick any of the garden snakes
Please do pet any of the garden snakes
然后返回:
Please [don't|do] [kick|pet] any of the [cats|dogs|garden snakes]
更多详情
- 我一直在研究最长的公共子字符串算法,但这似乎只比较两个字符串。
- 我只对比较字符串中的整个单词感兴趣。
- 只想从左到右评估字符串。
- 不常见子串的长度不会是相同的单词数(“cat” vs “garden snake”)
我正在寻求算法方面的帮助。我相信这是 LCS 问题的变体,我认为是对后缀树的某种处理。可以解释和实现的伪代码是理想的。
另一个例子
Please join thirteen of your friends at the Midnight Bash this Friday
Don't forget to join your friend John at the Midnight Bash tomorrow
Don't forget to join your friends John and Julie at the Midnight Bash tonight
变成:
[Please|Don't forget to]
join
[thirteen of your friends|your friend John|your friends John and Julie]
at the Midnight Bash
[this Friday|tomorrow|tonight]
也许这种方法
这种方法怎么样...
for an array of sentences
loop with the remaining sentence
find the "first common substring (FCS)"
split the sentences on the FCS
every unique phrase before the FCS is part of the set of uncommon phrases
trim the sentence by the first uncommon phrase
end loop
