In this question you will demonstrate your understanding of the Node ADT. It had the following operations: • create (data, next). • get_data (anode) • set_data (anode, val) ⚫ get_next (anode) • set_next (anode, bnode) This question has 4 parts. Each part is based on the same set of assumptions, as follows. Assume that you have a variable called head which stores a reference to a Node, and that Node record begins a chain of Nodes; for this question, head is not None. You do not need to write a function for any of the parts, nor any doc-string. A few lines of Python code are enough. Assume that the Node ADT has been imported as Node. (a) Write a code fragment in Python to remove the first Node, starting at head. After your script is done, the variable head should refer to the nodes that are still in the chain after removing the first node. (b) Write a code fragment in Python to add a new Node (with the value 42) to the front of the node-chain starting at head. After your script is finished, the variable head should refer to all the nodes in the chain after adding the new node. (c) Write a code fragment in Python to add a new Node (with the value 42) on the end of the chain starting at head. After your script is finished, the variable head should refer to all the nodes in the chain after adding the new node. (d) Write a code fragment in Python to add a new Node (with the value 42) at the midpoint of the chain starting at head. You may assume that the node-chain starting at head has 10 nodes, and that the new node has to be added after the 5th node in the chain. After your script is finished, the variable head should refer to all the nodes in the chain after adding the new node. (e) Write a code fragment in Python to remove the 7th Node of the chain starting at head. You may assume that the node-chain starting at head has at least 10 nodes. After your script is finished, the variable head should refer to all the nodes in the chain after removing the 7th node.
