Explanation of Solution
Quick sort:
- This is sorting
algorithm in which it sorts the array by dividing the list into two sub lists. - After dividing the lists, choose the pivot element between the lists.
- After selecting the pivot element, the algorithm reorders the values in the array until all the elements in left sub list is lesser than the pivot.
- Next, it sorts all the elements in the right sub list which are greater than or equal to pivot.
- Then, this algorithm recursively repeat the steps on sub list 1 and sub list 2...

Selection sort is a sorting algorithm, like Bubble sort which you saw in the previous module. Selection sort works as follows:
Selection sort divides the input list into two parts: a sublist of sorted items (left part) and a sublist of still unsorted items (right part). Initially, the sorted
sublist is empty and the whole input consists of the unsorted sublist. To fill the sorted sublist, the algorithm computes the (index of) the minimum of the
unsorted sublist and swaps the first unsorted element and the minimum element (if the minimum is already the first element, nothing happens).
Afterward, the sorted sublist is one bigger. This continues until the unsorted sublist is empty and the entire input is sorted.
Example:
Sorted sublist
Unsorted sublist

A binary search only works if the values in the list are sorted. A bubble
sort is a simple way to sort entries. The basic idea is to compare two
adjacent entries in a list-call them entry[j] and entry[j+1]. If entry[j] is
larger, then swap the entries. If this is repeated until the last two entries
are compared, the largest element in the list will now be last. The smallest
entry will ultimately get swapped, or "bubbled" up to the top. The
algorithm could be described in C as:
last = num;
while (last > 0) {
pairs = last – 1:
for (j = 0; j entry (j+1]
{
temp = entry[il:
entryli] = entrylj+1];
entrylj+1] = temp;
last = i:
}
}
Here, num is the number of entries in the list. Write an assembly
language program to implement a bubble sort algorithm, and test it using
a list of 8 elements. Each element should be a halfword in length. Please
show your code works with the Keil tools or VisUAL, by grabbing a screen
shot with your name somewhere on the screen.
Write a version of the sequential search algorithm that can be used to search a sorted list.

Both functions must take a list of integers as the input parameter.1) Bogosort: first shuffle the list argument (i.e., randomize the positions of every element) and then check to see if the result is in sorted order. If it is, the algorithm terminates successfully and returns True, but if it is not then the process must be repeated.2) Bozosort: choose two elements in the list at random, swap them, and then check if the result is in sorted order. If it is, the algorithm terminates successfully and returns True, but if it is not then the process must be repeated.Write a main() function and call both sorting functions using the same list as their arguments.

This algorithm finds the sublist that might contain the given item and divides it into three smaller sublists of almost equal size. The algorithm repeats this process until it finds the item or concludes that the item is not in the list. Analyze your algorithm and give the results using order notation.arrow_forwardThe 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.arrow_forward
