Time Limit: 10 Seconds Memory Limit: 32768 KB
You, as a member of a development team for a new spell checking program, are
to write a module that will check the correctness of given words using a known
dictionary of all correct words in all their forms.
If the word is absent in the dictionary then it can be replaced by correct words
(from the dictionary) that can be obtained by one of the following operations:
- deleting of one letter from the word;
- replacing of one letter in the word with an arbitrary letter;
- inserting of one arbitrary letter into the word.
Your task is to write the program that will find all possible replacements from the dictionary for every given word.
Input
The first part of the input contains all words from the dictionary. Each word
occupies its own line. This part is finished by the single character '#' on
a separate line. All words are different. There will be at most 10000 words
in the dictionary.
The next part of the file contains all words that are to be checked. Each word
occupies its own line. This part is also finished by the single character '#'
on a separate line. There will be at most 50 words that are to be checked.
All words in the input (words from the dictionary and words to be checked) consist
only of small alphabetic characters and each one contains 15 characters at most.
This problem contains multiple test cases!
The first line of a multiple input is an integer N, then a blank line followed by N input blocks. Each input block is in the format indicated in the problem description. There is a blank line between input blocks.
Output
Write to the output exactly one line for every checked word in the order of
their appearance in the second part of the input file. If the word is correct
(i.e. it exists in the dictionary) write the message: "
The output format consists of N output blocks. There is a blank line between
output blocks.
