Convex Hull

For a given set of points S in a plane, the convex hull is a line completely enclosing all the points within the plane such that no concavities are left. In other words, the convex hull of a set of points is the smallest convex polygon consisting of all points within the plane.

Tree Define a class called TreeNode containing three data fields: element, left and right. The element is a generic type. Create constructors, setters and getters as appropriate. Define a class called BinaryTree containing two data fields: root and numberElement. Create constructors, setters and getters as appropriate. Define a method balanceCheck to check if a tree is balanced. A tree being balanced means that the balance factor is -1, 0, or 1.

In a graph, two vertices are connected if there is a path between them. If all vertices are connected, we say the graph is connected. Given the Graph ADT below: class Graph { public: void addEdge (int vl, int v2); void delEdge (int vl, int v2); bool hasEdge (int v1, int v2) const; VList adj (int v) const; int v() const; int e() const; } ; Fill in the function isConnected that tells whether graph g is connected or not. Note that you can only use the above methods for g. You may assume vertex ID starts from 0 and define other helper functions if necessary. bool isConnected (const Graph &g) { // Copy this function in the answer and add code below this line.
