Match the sorting algorithms with their corresponding computational complexity. bubble sort O(n^2) selection sort O(n^2) insertion sort O(n^2) merge sort O(n^2)

The implementation of a queue in an array, as given in this chapter, uses the variable count to determine whether the queue is empty or full. You can also use the variable count to return the number of elements in the queue. On the other hand, class linkedQueueType does not use such a variable to keep track of the number of elements in the queue. Redefine the class linkedQueueType by adding the variable count to keep track of the number of elements in the queue. Modify the definitions of the functions addQueue and deleteQueue as necessary. Add the function queueCount to return the number of elements in the queue. Also, write a program to test various operations of the class you defined.

(Sorting) Read a set of numerical grades from the keyboard into an array. The maximum number of grades to be entered is 50, and data entry should be terminated when a negative number is entered. Have your program sort and print the grades in descending order.

(Practice) Write a C++ program that adds equivalent elements of the two-dimensional arrays named first and second. Both arrays should have two rows and three columns. For example, element [1][2] of the resulting array should be the sum of first [1][2]andsecond[1][2]. The first and second arrays should be initialized as follows: first second 16 18 23 24 52 77 54 9111 16 19 59

(Data processing) a. Write an algorithm to locate the first occurrence of the name JEAN in a list of names arranged in random order. b. Discuss how you could improve your algorithm for Exercise 7a if the list of names were arranged in alphabetical order.

(Numerical) Determine and write an algorithm to sort four numbers into ascending (from lowest to highest) order.
