You could try to explain yourself a little better. Six words is just too little to understand what you need...
I need some document that explains the Range Tree
Ahhhhhh, OK.
On Topcoder in the tutorial for LCA, there's a section that explains the use of segment trees -> http://community.topcoder.com/tc?module=Static&d1=tutorials&d2=lowestCommonAncestor#Segment_Trees
This one has a little more info -> http://wcipeg.com/wiki/Segment_tree
And if you want more technical details, there's the Wikipedia article -> http://en.wikipedia.org/wiki/Segment_tree
You might want to know about lazy propagation too if you're gonna learn range trees.
ok, thank you
