Print the section of TEXT that contains the longest hidden WORD

How to resolve a tie when there are multiple hidden words found, and the hidden words have the same length?

The situation isn’t supposed to arise. Have you found such a case?

Needs better test cases please… I am able to pass all test cases but my script fails validator 03 “Be puntcual” (<-- typo btw) and 04 “Tempus fugit”

At this moment, your current test cases may not have the tie situation. But you still have the responsibility to define the specification to close all loopholes. Test cases can be updated or added later by anyone. Coders often define their own test cases for debugging too. People adding a test case rely on your statement to determine what is acceptable.

You can specify such a tie situation is not allowed. You can define further rules to resolve any tie situation. Anything is better than doing nothing.

I have edited the description to specify there will be no such ties.

Fixed the typo.
What kind of failure? Do you get a different answer, or a timeout? Can you share your code?

I think it shouldn’t be in easy section ! It’s way more difficult than the other problems in this section.

Thanks for the reply. I’ve sent you my code and screenshots via direct message :slight_smile:

I was a bit afraid about the thousandesque numbers in the constraints because it means that you have to pay attention to your time complexity but actually it wasn’t that complicated.

What makes it definitively not too hard is that the step is always the same between letters of an hidden word.
Focusing on this makes the searching method quite straightforward.

I have added a test case to help you through validator 4.

I first failed only validator 1 because I interpreted evenly as the space between letters is an even number.
I had to look at the validator to understand that the spacing was odd.

Ha - I didn’t even notice all the tests happened to have spacing with the same parity! I’ve edited one of the test cases to avoid that.

When it says “ignore punctuation, capitalization, and spacing” does that mean that after converting to all lowercase it’s safe to remove all characters in the TEXT and WORDs other than the letters a-z before starting to look for an answer? I’m doing that and pass all five test cases, but I fail “Be punctual” and “Tempus fugit” when I submit. You’re sure there are no ties, right? I’m sorting the WORDS by length descending before starting to look for an answer and stop immediately on the first match.

If you’ll share your code, I don’t mind running it to see if it’s an incorrect answer or an optimization issue that times out.

Thanks! I have passed all validators now! appreciate it very much.

I solved it first in Python and encountered no problems at all. But then my solution in C++ did get timeout with fourth validator. Working neither with the same algorithm as I used in Python, nor with a slightly optimized one. I think I have to ditch the C++ “string” data type for the “char *” and write my own search function that is based on Boyer-Moore string-search.
