Nearest vertex in a tree with a smaller value
You are given a tree of $$$N<=10^6$$$ vertices. Each vertex of the tree contains a number $$$a[i]<=10^9$$$.You are given $$$M<=10^6$$$ queries: "Find the distance to nearest vertex to the vertex $$$V$$$, with the value less than $$$X<=10^9$$$?"
How this problem can be solved?
