The program should be able to insert, delete and display nodes in the queue. The user will be asked to enter his choice either to insert a node (enqueue), delete a node (dequeue), display or to exit from the program.The options for the user should be as the following:1. Insert a node (Enqueue)2. Delete a node (Dequeue)3. Display4. Exit For example if user selected option 1 then the following should appear in the output:Enter the value to insert:Node is inserted If user selected option 2 then the following should appear in the output:Deleted Element is: If the user selected option 3 then the program should display the elements that are available in the queue The program will keep on running and taking inputs from the user until he selects the 4th option to exit.Please develop well-documented pseudo code that finds all consecutive similar elements of a given array (of any size n) by using either a stack or a queue. The code must display the start indices where the values start to repeat, as well as the values of these elements. For instance, given the following array A: (22, 9, 61,61, 61, 21, 0, 9, 9, 9, 9, 35, 81,81, 9, 5, 5), the code should find and display something similar to the following (pls notice that this is just an example. The solution must not refer to this particular example): Value 61 is repeated 3 times starting at Index 2 Value 9 is repeated 4 times starting at Index 7Value 81 is repeated 2 times starting at Index 12Value 5 is repeated 2 times starting at Index 15 a) Briefly justify the motive(s) behind your design. b) What is the Big-O time complexity of your solution?
