suppose i have a list containing a whole book, the list will contain
words, sentences, chapters; as an example:
lst={{{"abc","def"},{"as","red"}},{{"fat","qqq","qqq"},
{"asd","asd","vbn"}},{{"zz","zz"}},{{"zz","wtt","wtt"}},{{"red","zz"},
{"sd","ed"},{"er","to"}},{{"ww","ww","dff"},{"as","end"}}}
please check sometimes some servers may insert the false "-" letter
in the above lst.
here is the book lst contains six chapters, 11 sentences,
the question is: what are the general methods wich could be used to
know how many words, and how many sentences and how many chapters
between an arbitrary two words in the book such as an example:
between the word number 2 in sentence 2 in chapter 2
and the word number 2 in sentence 1 in chapter 5
ie:
wrd1=lst[[2]][[2]][[2]]
wrd2=lst[[5]][[1]][[2]]
the results will be: if we count the 2 words and their own sentences
and chapters:
9 words, 4 sentences, 4 chapters.
reards.
