Exercise books in analysis I'm studying Rudin's Principles of mathematical analysis and I was wondering if there are some exercise books (that is, books with solved problems and exercises) that I can use as a companion to Rudin. 
The books I'm searching for should be:


*

*full of hard, non-obvious, non-common, and thought-provoking problems;

*rich of complete, step by step, rigorous, and enlightening solutions;
