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.
