Cutting boxing is an interesting part of ancient Chinese wine culture. On the wine table, you can draw a number in each user's mouth and draw a number by hand. If the sum of the numbers is equal to the sum of the numbers shouted by the two, the loser will win the prize. If the two win the same game or both lose the same game, the next round will continue until the only winner appears. The following is a row-cutting record for the first and second students. Please count how many drinks they final

Find out the two vertices so that the tree is the farthest from the two vertices to the two vertices (just a certain point in the tree). Ideas: Find the tree diameter, find the midpoint, delete the edge in the middle (if the number of points on the diameter is odd, delete any side), divide it into two Subtrees, and then find the center, that is, the answer.
