I was looking for some good tutorial on B-trees. I am new to this data structure and would like you explore it in detail. Any suggestions?

And also I'd like to ask, if there exist ACM-like problems, where that is absolutely necessary to implement such complicated data structures as B/B+/AVL/Red-Black trees on your own and set/map can't be used instead.

I recommend you those vidoes, are about balanced search trees (including B-Tree).
