Hello, Codeforces!

We are happy to invite you to CPA Community Groups which contains many problems on many topics for you to exercise and improve your algorithms knowledge.

Our goal is to make a pathway for everyone to reach their aim with only a Codeforces account !

It currently contains these topics (with 100+ problems):

• Prefix Sums

• Custom Comparators

• Coordinate Compression

• Two Pointers

• Sorted Sets

• Greedy Algorithms

• Binary Search

And we have reformatted these problems to make it more readable (I think) from the original sources !

We will add more problems and more topics in the future, hope that you guys enjoy it.

We currently just summarize problems from USACO Guide, we think that we will summarize more problems from more sources. The reason why we summarize problems from USACO Guide is because we know that not many people have the account on USACO and many other platform and those problems are really good for exercising.

Join Discord Server ! (for discussing about CP problems and we will make some video and living tutorial for these problems).
