Hi please find the solution below and I hope it would be helpful for you.

Implement find_level, which takes a tree t and an integer level and returns a list of all the values that have depth level. If no such values exist, return the empty list. For a refresher on the depth of a node, check out here.

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.

6. Suppose that we have defined a singly linked list class that contains a list of unique integers in ascending order. Create a method that merges the integers into a new list. Note the additional requirements listed below. Notes: ● . Neither this list nor other list should change. The input lists will contain id's in sorted order. However, they may contain duplicate values. For example, other list might contain id's . You should not create duplicate id's in the list. Important: this list may contain duplicate id's, and other list may also contain duplicate id's. You must ensure that the resulting list does not contain duplicates, even if the input lists do contain duplicates.

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. You see two linked lists here??? Yes! You’ll need to use the linked lists
