I followed this post http://mirror.codeforces.com/blog/entry/18051 to learn segment tree and I really like the implementation, but can't figure out how to implement fractional cascading. Any idea ?

from my experience, segment trees with fractional cascading are somehow not faster than usual segment trees. Use persistent ones.
