Part $2$: SingleLinkedList

Assume the SingleLinkedList class, which is similar to the java built$-$in class, is given to you $($as discussed in the lecture, and the complete class is uploaded on the blackboard$),$ write the implementation of the following methods:

a$.$ Write a method called ListConcatenation within the class that has two parameters listA and listB of type SingleLinkedList. The method should modify listA by copying the nodes from listB to listA $($starting from the end of listA$).$ Assume both lists are non$-$empty.

The method head is

public void ListConcatenation $($SingleLinkedList listA, SingleLinkedList Before calling the method: myList : $7,10,14,20,243,6,8,12,17,21>$ listB
