You have to use this code also:

#include using namespace std; #include "GRAPH.h"

void main() { char vertex[] = {'S', 'R', 'G', 'B', 'O', 'T', 'V'}; int numVertices = sizeof(vertex)/sizeof(char); GRAPH g(vertex, numVertices);

g.setEdge('S', 'R', 10, true); g.setEdge('B', 'S', 80, true); g.setEdge('S', 'T', 120, true); g.setEdge('G', 'R', 40, true); g.setEdge('R', 'O', 60, true); g.setEdge('R', 'V', 120, true); g.setEdge('R', 'T', 90, true); g.setEdge('O', 'G', 100, true); g.setEdge('G', 'B', 30, true); g.setEdge('O', 'B', 80, true); g.setEdge('T', 'O', 20, true); g.setEdge('V', 'T', 30, true);

cout

Enter integers through the keyboard. While entering the numbers, create a binary search tree. For a NULL node enter - 1. For the created binary tree write its preorder, inorder, postorder and level order traversals. Then, add a function to find the node with the qreatest value in the tree (its value and address). If the first value that is entered is equal to 1, then don't print the tree, its traversals or the node with the greatest value, but instead only print a message that the tree is empty. Example output
