He deletes any number (possibly 00) of edges from the tree and computes the product of the sizes of all connected components after the deletions. L scores that many points. Your task is, for a given tree, to find the maximum score L can obtain.

Input Format

The first line contains an integer nn, the number of nodes in the tree.

The next (n1)(n-1) lines each contain two integers u,vu, v, indicating that there is an edge connecting uu and vv.

Output Format
