Hello,↵
↵
Can someone explain the solution to USACO newbarn (Problem: http://www.usaco.org/index.php?page=viewproblem2&cpid=817, Solution: ↵
http://www.usaco.org/current/data/sol_newbarn_platinum_feb18.html)? I don't understand what his variables names mean, like tree[c].top, tid, etc. Can someone explain what all of his variables mean and how each part of his program works, including his centroid decomposition? Thanks!↵
↵
Edit: OK, if anyone has a centroid decomposition solution that's not the official solution (I can't understand how the checking for the same subtree idea works), can you post it and explain it in depth?↵
