Hello everyone!

I created this simple training that contains 100 Problems "graphs, dfs and similar, dsu".

Difficulty of problems from 1200 to 1700

Group link: Graphs Problems

**Group ratings**

**Some other trainings**

Welcome all suggestions for improving training

Good luck everyone!

Oh,that's really good!

"Graphs, dfs and similar, dsu" ----> this is really important for beginners!

Thanks. :)

They are very useful. I will learn a lot from these questions. Well done :)

You got what you wanted: my upvote.

Sounds cool (:Could u make a list of string problems?Problem 1: A + B (String version)

Take in two strings and concatenate them in sub-O(n) time.

Constraints: |A|, |B| <= 1e9

How do pick the problems ? I think a 1200 problem that involves core graph knowledge is not very likely to exist.

I Choose problems by PROBLEMSET => Filter Problems.

Examples of graphs problems of difficulty 1200 :

Please share some Graph Tutorials in Java. Any Youtube series or Graph course will surely help. Thank you.

I think this is pretty good for both C++ and Java users.

could you make one on DP??

Thank you

Thanks, sir

haha this is helpful since i can solve problems of any rating without knowing.. i wont be scared when i see a high rating. thanks!
