43. In this question you will demonstrate your understanding of node chains (Assignment 5), by writing simple scripts; your answers do not need to define any functions. For each of the following questions, assume that you have a node-chain of at least 100 nodes (i.e., too long to display or give a visual example), starting at a variable named anchor. To answer this question you may assume the following import statement import node as node (3) (a) Write a Python script to add a new node with the data value 42 to the front of the chain. When the script is finished, the variable anchor should refer to the new chain with the new node added. (2) 6) Write a Python script to remove the first node the front of the chain. When the script is finished, the variable anchor should refer to the new chain without the node (which was previous first, but no longer in the chain). (4) (c) Write a Python script to add a new node with the data value 42 to the end of the chain. When the script is finished, the variable anchor should refer to the new chain with the new node added. (3) (d) Write a Python script to remove the node at the end of the chain. When the script is finished, the variable anchor should refer to the new chain with the node removed. NSID: (4) (e) Write a Python script to add a new node with the data value 42 at index 42 in the chain (this is a simplified version of an assignment question; as in the assignment, assume that the first node in the chain is at index 0). When the script is finished, the variable anchor should refer to the new chain with the new node added. (3) (f) Write a Python script to remove the node currently at index 42 in the chain (as in the previous question, assume that the first node in the chain is at index 0). When the script is finished, the variable anchor should refer to the new chain with the node removed
