My (and others') solutions to Sheldon Axler's Measure, Integration & Real Analysis.
Go and check out the book here, it's peak. #625 recommended it 100%.
Tedious problems (that provides not really much insights) were skipped, sorry.
Many solutions here are mostly taken from Math Stackexchange, but I forgot where they were from, sorry. I will try to credit people more, I guess. Hence, this is released under public domain.
A lot of hidden assumptions were omitted in the proofs, so some proof might feel unrigorous at times, not to mention my carelessness too.
