Question

c)Define a class that implementsa singly linked list with the following methods, assuming that the first node of a linked list is referred to by head:
i) A constructor.
ii) searchNode that takes asparameter an integer value and returns a reference to the node with that value if it is found,and null otherwise.

i)addlnOrder that allows insertion of a node to the linked list such that the list remainssorted in ascendingorder.
iv) displayList which displays all the nodes in the linked list.
d) Assuming that the class defined in part (c) aboveis used to implement a queueof
positive integers, define the following methods which can be used to implement queueoperations:
i) isEmptythat returns true if the queue is empty andfalse otherwise.
ii) pop that returns the value of the first node if the linked list is not empty,and -1 otherwise.
iii) push that takes as parameteran integer value and adds it to the end of the queue.
