Which book should one read together with Real Analysis by H. L. Royden and P. M. fitzpatrick, 4th edition, so that the former book (i) elaborates and clarifies the details omitted in the proofs in the latter, and (ii) contains solutions to some, most, or all of the exercise problems in the latter?
Are there any course webpages --- featuring lecture notes, problem sets with solutions, and video lectures --- for any undergrad-level courses based on Royden?
