Step 1 is already done, need help with Step 2. Step 1 is listed below.

Step 1: Rewrite the starter code, GuessBirthdayStarter.java, to prompt the user to enter the character Y for Yes and N for No rather than entering 1 for Yes and 0 for No.

Step 2: Rewrite the code again, but this time allow the user to enter at least 3 different characters, words, or expressions to agree to the prompt and 3 different expressions to disagree. Include a comment that lists all allowable inputs and validate your changes to the starter code
