Note this problem was originally intended for the cancelled 2020 Girls Invitational Competition.

Yvonne Zhang loves to give high fives. She's picky about who she will high five and will only high five a certain ~N~ times a day. However, Yvonne also forgets the number of times she high fives in a day. Can you determine if Yvonne is correct about the amount of high fives she gives in a day based on the following criteria?

• Yvonne Zhang loves even numbers. She will only high five an even number of times by the end of the day.
• Yvonne likes to high five each person 3 times in a row. (Hint: the total number of high fives Yvonne gives will be a multiple of 3.)
• Yvonne has a fear of the number 2. The number of times she high fives by the end of the day will never end with the ones digit of '2'.
