I am poor and can't afford internet. I am good at basic data structure. Now learning algorithm. I have 1-2 ICPC attempts. I want to go to the WF.

Where can I find CSES/UVa problemset and solution in PDF?

E: I don't know why I'm getting downvoted. My data pack will expire in few days and I can't find any OFFLINE problem books by Googling. That's why I am asking here.
