Algorithm for Robotic sort problem
By amit.codename13, 16 years ago, In English
I am trying to solve this problem,

http://acm.uva.es/archive/nuevoportal/data/problem.php?p=3961

I can think of a O(n2) algorithm but its too slow for this problem. 
I think some data structure built with trees and linked list should solve this problem
Can anybody give some hints/ideas for this?
