Problem Description Given a tree of N nodes. The N-1 edges are given in a 2D integer array A. Find the number of simple paths that do not share an edge or a vertex with the longest simple path in the tree. Since the answer can be large, output it modulo 10° +7. Note: • If there are multiple longest paths, choose the one with the further endpoint from 1 and the largest node value possible. Secondly, in case of still multiple longest paths, again choose the second endpoint as the largest node value possible. ● Problem Constraints 2 <= N <= 105 Input Format

Question
please answer in any language and asap plsss
Example Explanation
Explanation 1: The longest path in the tree covers all smaller paths. Explanation2:The longest path is1−2−3−4−5−6−7−8−9−10
The six shorter paths that are not part of the longest path are: 11 to 12,11 to 13,11 to 14,12 to 13,12 to 14,13 to 14 .
