An USACO probem
By AFatWolf, history, 9 years ago, In English

Recently I've been trying to solve a bronze USACO problem ( The problem is exploration — the first one at this site: http://tjsct.wikidot.com/usaco-nov07-bronze ).

After understading what do they ask, I now could easily solve it. But what if the statement changes to finding the maximum point we can reach, will there be any solutions?

Thanks in advance :D

P/s: sorry if my english are poor.

Actually it's not greedy solution. Problem exactly asks it.

    I thought it was greesy when they choose the point nearest to point 0?

          The problem ask you to go to the point that is 1. Closest to the origin, at cordinate 0. 2. Unvisited before. So I think the solution is quite straight forward. There is no greedy in the solution, just simple implementation.
