Hello,

I was trying to do the USACO problem Grass Planting (http://www.usaco.org/index.php?page=viewproblem2&cpid=102), but couldn't get my Heavy Light Decomposition to work. Can somebody direct me to a Heavy Light Decomposition implementation without LCA? Also, could someone also show me how to implement Heavy Light Decomposition with both the values on vertices and then with the values on the edges? I tried using Al.Cash's implementation, but for some reason, it failed. Thanks!
