We do like people to show appreciation, that is true.
And I thank you for yours.
HOWEVER
We also want to help people learn. When people ask a lot of questions in a short period of time as you have done it is fairly clear to me that you are primarily using this site as a cheat site. You are getting our well meaning answerers to do your homework for you.
This assessment is backed up by your not asking ANY of the answerers any questions at all about their solutions. You have not interacted with them in any way.
It depresses me when this site is used/abused like this.
