Refer to the tree on the picture and answer the following questions 1. Aside from its children, list 2 other descendants of node C. Your answer must be values that are adjacent when the nodes are arranged alphabetically in ascending order. For example, the descendant nodes are: ABX Y. You cannot answer A X since you have skipped B and B Y since X has been skipped. * 2. What is the path from node A to node L? * 3. What is the length of the path from node C to node N? Note: answer with the number's symbol and not the word form of the number.* 4. List 2 nodes that are at level 2 of the tree. Your answer must be values that 1 point are adjacent when the nodes are arranged alphabetically in ascending order. For example, the nodes at a certain level are: A B X Y. You cannot answer A X since you have skipped B and B Y since X has been skipped. * 5. What is the height of the tree? Note: answer with the number's symbol and not the word form of the number.* 6. What is the height of node C? Note:…
