Given an input String, first decide if the String contains "I (something) you", like "I will find you". If it does not contain "I (something) you", return "I don't understand". Note that "I (something) you" could occur anywhere in the input. If it does contain "I (something) you", return a response that includes part of the input in the form "Why do you (something) me?" If you are still confused, see the input/output test cases. Note that "I " must be BEFORE " you" in the input in order to work correctly. Also note that specific space characters are integral parts of what to look for in the input, not just the letters.

HINT: use indexOf to find the desired two patterns, and remember their locations. Use substring to capture a portion of the input, which becomes part of the output.

CHALLENGE: solve in one statement, which can pretty easily be done with a ternary operator.
