Oh,that's really good!

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

Thanks. :)

    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.
