      I failed on test 67, beacause I wasn't paying attention to the case "YES" of only one word. Then I checked that case and I failed on a testcase around 200: I checked my code for bugs, I corrected and it worked. So I suppose it is for the "only one word" case. But that's weird cause it seems you check that case

why don't you use test case 67 and print out results to see what's wrong? btw, there is another nice solution to this problem using regex. :)
