Graph Theory Task

Revision ru6, by gop2024, 2017-06-06 01:31:04

Can anybody help me with this task: We have a tree with N verteces(N<=5*10^5). Each edge has got a length Li(Li<=1000). In each iteration we delete one(given) of un-deleted edges and we must tell the longest simple way in each of two resulting components and we doing it while all edges aren't deleted. Please, any ideas how to solve it?
