Hello codeforces.

I wanted to have an hld problemset. there is no hld tags in cf.

so if you have an hld problemset or you know some hld problems I would be very thankful if you share them.

Easy:

Hard:

Also, lca problems might be helpful (since the common application of hld is just the same lifting, but along with queries to an internal data structure)
