Write a Node.js program that uses the quadratic formula to solve for the two values of x, given a = 1, b = -8, and c = 5.
Consider the following function:int mystery(NodeInt32* node){int counter = 0; while (node != NULL) {counter++;node = node->next; } return counter;}
Code in C++ only
In a rooted tree, the lowest common ancestor (or LCA for short) of two vertices u and v is defined as the lowest vertex that is ancestor of both
that two vertices. Given a tree of N vertices, you need to answer the question of the form "r u v" which means if the root of the tree is at r then
what is LCA of u and v.
