Implement the InOrder traversal method discussed in class, which shows the keys of the BST in increasing order Insert 1, 2, 3, 4, 5, 6, 7, 8,9, 10, 11, 12, 13, 14, 15 in the tree (in that order). Show all keys in the tree (for this and the following, use the InOrder traversal method you implemented Perform find(1) and find(15) 100,000 times and record the CPU time taken by each of these. Remove key 5. Show all keys in inorder traversal. Remove 15. Show all the keys in inorder traversal. Remove 1. Show all the keys in inorder traversal. Insert key 2. Show all keys in inorder traversal
