Dear teachers, I am curious if you know some good books that have problems well supplemented to "Commutative Algebra I-II" by Zariski/Samuel. I am really enjoying it, but it does not have any exercise, leaving me to try coming up with my own problems (it is fun to do, but I would like to solve some concrete problems too). Essentially, I would like books that contain a lot of problems about commutative algebra to supplement Zariski/Samuel (I am not planning to read those supplementary books). Also, is it a good idea to read a book in the computational commutative algebra along with Zariski/Samuel? I am very interested in studying Grobner basis, which Z/S does not have.
