Best practice book for calculus [closed]

I tried with every inch in me to not ask a question such as this but I just couldn't resist asking this.

What is the best Calculus practice book?

I tried looking around but couldn't find a decent consensus on one book or even a few. It would be great if someone could point me towards a book that has both challenging and fun problems and furthermore, allows the student to build a strong foundation while doing those problems.

Thanks a bunch!

• Collection of problems in analysis by B.P. Demidovich
• Problems in Mathematical Analysis B.P. Demidovich

These books are very famous here in Brazil. It's very organized and easy to get addicted.

Somewhere in 3k problems you should cover almost everything

Problems in Calculus of One Variable, with Elements of Theory by IA Maron is good for problems as well as revising single variable calculus.
