Hello,

I googled it but I couldn't find any example about how segment trees are used in real life applications. can you give any examples? are there any well-known applications that use segment trees?

Thanks.

Hello,

I participated the codechef july cook-off last weekend and I couldn't manage to solve the second question (http://www.codechef.com/COOK24/problems/CIELMAP/).

Here is my submission; http://www.codechef.com/viewsolution/1190738.

Can anybody say what I'm doing wrong in my code?

Thanks.

PS: If you could recommend any geometrical algorithm resources, I'll appreciate.
