小编use*_*171的帖子

我正在编写一个函数,try-weak-cues用于从大量响应中选择响应.该程序本质上是与用户的对话.

(define try-weak-cues
        (lambda (sentence context)
        (define helper
           (lambda(list-of-pairs)
          (define helper2
            (lambda(list-of-pairs context)
              (cond((null? list-of-pairs)
                  (cond((null? list-of-pairs) '())
                       ((any-good-fragments?(cue-part(car list-of-pairs))sentence) (helper2(cdr(car list-of-pairs))context))
                        (else(helper(cdr list-of-pairs)))))))))
                       (helper *weak-cues*))))

下面是该函数应该从中获取的响应列表:

 (define *weak-cues*
  '( ( ((who) (whos) (who is))
       ((first-base)
           ((thats right) (exactly) (you got it)
        (right on) (now youve got it)))
       ((second-base third-base)
           ((no whos on first) (whos on first) (first base))) )
     ( ((what) (whats) (what is))
       ((first-base third-base)
       ((hes on second) (i told you whats on second)))
       ((second-base)
       ((right) …

我似乎在删除结构列表中的重复项时遇到了一些问题.

这是结构的一个例子:

struct item 
{
    String name;
    int index;
    String type;
}

我想这样做,以便从列表中删除具有相同名称,索引和类型的项目,并且我想在清除其他方法的重复项后使用相同的列表,我只是不完全确定如何做这个.
