:) - What slav will not check...

What do you mean by that?

I meet this trouble too,I don't understand ,the program should failed or successful completely,why it can just pass 3 test cases?
I forgot some idea that the problem say?

I guess that if your program think the  word's  count of the result  is short than the word you read ,then you can't pass the 3 group test cases :)
for example,you read 3 word "it"、"is"、"ok",but the answer is "it it it it",if your program return "No Solution" in this situtation,in this case ,it will fail。
