Programing C Just with #include Creating a Tree In this challenge, you will have to use pointers to create a tree. More specifically, the tree shown below: n1 n2 n3 n4 "end" "end" n5 "end" n6 "end" n7 "end" "end" "end" "end" "end" "end" "end" "end" "end" "end" "end" should be the same end we discussed in class for singly linked lists In other words, you will have to create structures that contain one value and three pointers. You will then have to declare your nodes and have their pointers (arrows), point to the nodes specified in the three. You will do this in the exact same way as we did with linked lists. The differences here are that you have more pointers and a different layout of the nodes. Your program should not print anything. It is merely meant to show your understanding of pointers and “nodes" (structures). Therefore, aside from the definitions of your structures, everything should be in main.
Write C++ program to represent a complete binary tree as an array. Your program should ask the user to enter an index. Print parent, left child, & right child of the node at the entered index.
4. Write a recursive algorithm in pseudocode that finds the lowest common ancestor (LCA) of two given nodes in a binary tree T. The lowest common ancestor is defined between two nodes p and q as the lowest node in T that has both p and q as descendants (where we allow a node to be a descendant of itself). If either p or q is null, the LCA is null. For this problem, Nodes have left, right, and parent references as well as a field called level which stores the level of the node in the tree. In the sample tree below, node 5 is on level 0, while nodes 4 and 6 are on level 1. Write your solution here. 5 <- level 0 4 6 < level 1 function lowest_common_ancestor (Node P, Node q)
