WebJan 9, 2010 · Pick a large prime number H (that's greater than maximal number of children). To hash a tree, hash its root, pick a child number H mod n, where n is the number of children of root, and recursively hash the subtree of this child. This seems to be a bad option if trees differ only deeply near the leaves.
