CF Automatic Mashup Generator bởi Everest

This is a tool to make custom codeforces mashup contests for practice without any hassle, you just put in your handles select the rating range and how many problems you want, and it does the rest.

It automatically checks your submission history to avoid picking problems you have already solved, there is also a toggle to avoid problems with the same name, so you dont get repeats from old gym contests, you can easily filter out specific types of rounds like icpc or normal rounds , choose if you want the problems sorted by difficulty or completely random, and from new to old or old to new or random.

It also has built-in spoiler protection that hides out the problem tags and ratings on the mashup page, so you dont get accidental hints before solving, all your settings and handles are saved locally, so you dont have to re-type everything every time you want to practice .
