我正在努力在Swift中概括这个示例代码:
python manage.py migrate
目的是按顺序获得包含一个a字,一个b字和一个c字的所有组合。但我希望能够将其概括为任何序列(即acb,acdqp等)
理想情况下,我想传递一个字符串,如" acd"进入一个函数,返回一个匹配的句子数组。任何帮助将不胜感激!

我想出了一个解决方案。在Template
结构内:
func sentencesWithWords(words: [String]) -> [String] {
// Group vocabulary into set of template options
let optionsSets = template.map { descriptor in
return words.filter({ $0.matchesDescriptor(descriptor) })
}
// Iterate through options set
var sentences = [String]()
for options in optionsSets {
// Append each option to each existing sentence
var newSentences = [String]()
for option in options {
if sentences.count == 0 {
newSentences.append(option)
} else {
for sentence in sentences {
newSentences.append("\(sentence) \(option)")
}
}
}
sentences = newSentences
}
return sentences
}
