If this tree is empty, it raises an EmptyCollectionException. If the tree is empty, returning a reference to the node with the fewest values produces an EmptyCollectionException.Implement a Single linked list to store a set of Integer numbers (no duplicate) • Instance variable• Constructor• Accessor and Update methods 2.)

- C++ DATA STRUCTURES Implement the TNode and Tree classes. The TNode class will include a data item name of type string,which will represent a person’s name. Yes, you got it right, we are going to implement a family tree!Please note that this is not a Binary Tree. Write the methods for inserting nodes into the tree,searching for a node in the tree, and performing pre-order and post-order traversals.The insert method should take two strings as input. The second string will be added as a child node tothe parent node represented by the first string. Hint: The TNode class will need to have two TNode pointers in addition to the name data member:TNode *sibling will point to the next sibling of this node, and TNode *child will represent the first child ofthis node.
