Design your own 2-3-4 tree class

(3) Design your own 2-3-4 tree class [see 2-3-4 tree lecture for details about the operations] Your tree class should have the following operations, (i) Insert (ii) Delete (ii) Search (iv) Traverse (a) Inorder (b) Preorder (c) Postorder Input Format: The first line of the input contains Q, the number of operations. The next Q lines contain the operations that need to be performed. Following are the different types of operation, (i) Insert: 1 k [where, k is the key to be inserted] (ii) Delete: 2 k [where, k is the key to be deleted] (iii) Search: 3 k [where, k is the key to be searched] (iv) Traverse (a) Inorder: 4 (b) Preorder: 5 (c) Postorder: 6 Initially, the tree is empty Output format: After each 4, 5, and 6 output the corresponding traversal. For successful search output "successful", otherwise output "failed". For successful delete output "successful", otherwise output "failed". Sample Input: 12 13 12 1 6 4 18 19 17 110 4 3 12 Sample Output: 1236 1236789 10 11 failed
