I am not able to solve many questions relating to heavy light decomposition of tree,So please help me to understand the concept any links please to thoroughly understand HLD of the tree Thanx in advance
@adijimmy : An excellent link on Heavy light decomposition is
http://wcipeg.com/wiki/Heavy-light_decomposition < br>
Its really too much to write a big description of the technique that you like better than the above one .
So what I suggest is you read this link , take any one problem based on this technique and write some code and post the code link here on this thread
I will help you debug / implement the correct code on this thread for one problem so that you can understand the technique well .
