Q14. Write a selecting sort algorithm to handle the data 10,30,20,20,40.
Q15. Which type of data structure takes the same time to find an objects
irrespective of the objects given?
Design a function: int search (float a[ ], int n, float x); The function searches in array a of size n for the item x. If x is found , its index is returned, otherwise -1 is returned. Design the main function also.
this is a data structure algorithm question so read it properly and right correct answer please

- Write a program to test the sequential search algorithm that you wrote of this chapter. Use either the function bubbleSort or insertionSort to sort the list before the search.arrow_forwardIf array A consists only of values of 0, 1, and 2, design a function that sorts A. However, sorting should be done without comparing the records' keys. We approach array A by dividing the area into three places and placing 0, 1, 2 in each place. O goes from index 0, and 2 goes from the largest index. 0 The results before and after alignment are shown below. Before alignment = {0, 1, 1, 0, 1, 2, 1, 2, 0, 0, 0, 1} After alignment = {0, 0, 0, 0, 0, 1, 1, 1, 1, 2, 2}arrow_forwardComputer Science Represent the following sets by using BST: A={7,2,4,9,15,6,11}, B={12,3,16,1,5,8,10}.

- DO NOT COPY FROM OTHER WEBSITES Correct and detailed answer will be Upvoted else downvoted. Thank you!arrow_forward13. While dictionaries are designed so that we can find a value based on a key, every so often we need to perform a reverse lookup. For example, imagine a dictionary where the keys are names and the values are phone numbers. Usually we want to find the phone number based on the name, but occasionally you might need to find a name based on the phone number. Write a function called reverse_lookup(dictionary, value) that returns all the keys in the dictionary associated with the specified value. Note: In dictionaries, the keys are guaranteed to be unique, but the values are not. So your function should return a list containing all of the matching keys (if any) Example: Given this dictionary, groups = {'Apple': 'Fruit', 'Spinach': 'Vegetable', 'Banana': 'Fruit'} reverse_lookup (groups. Vegetable') ["Spinach'] reverse_lookup (groups, Fruit') ['Apple'. 'Banana'] reverse_lookup (groups. 'Meat') []arrow_forwardSubject: Data structurearrow_forward
- Use the Quick sort method as discussed in the note and video clip to sort the following items given in this order. Display all the steps of moving the pointers (L) and (R), switching of the items and the final placement of the Pivot up to the first partion. Use 21 as the Pivot. Pivot L R ↓↓ ↓ 21 6 14 35 27 10 47 31 19arrow_forwardAssume that empName and empID are two parallel arrays of size numEmp that hold employee data. Write a pseudocode algorithm that sorts the empID array in ascending ID number order (using any sort you wish), such that the two arrays remain parallel. That is, after sorting, for all indexes in the arrays, empName[index] must still be the name of the employee whose ID is in empID[index].arrow_forwardThis chapter's bubble sort method is less efficient than it could be. If a pass through the list is done without swapping any components, the list is sorted and there is no reason to continue. Change this algorithm to terminate as soon as it recognises that the list is sorted. A break statement should not be used.This chapter's bubble sort method is less efficient than it could be.

- Write a version of the sequential search algorithm that can be used to search a sorted list.arrow_forwardExercise 1:In this problem, we would like to implement a variation of the Bubble Sort algorithm. The algorithm differs from a bubble sort in that it sorts in both directions on each pass through the list. The algorithm is illustrated as in the following figure: For the first step, we perform bubble sort from the index 1 to n (n is thenumber of elements in the array). The next step, we perform a reserved bubble sort from the index n to 1. The process is repeated until all the array is sorted. Propose a pseudo-code to complete the Bubble Sort algorithm. Implement and test this algorithm in C/C++. Analyze and compute the complexity of this algorithm in the best, average and worst scenarios.Exercise 2:Re-implement Exercise 1 using a linear data structure: List, Stack, Queue. Justify your choice of data structure.arrow_forwardAlgorithm Analysis1. Revises the function quickSort so that it always chooses the first item in the array as the pivot. Add a counter to the function partition that counts the number of comparisons that are made. Compare the behavior of the revised function with the original one (pivot should be selected using sortFirstMiddleLast algorithm), using arrays of various sizes. At what size array does the difference in the number of comparisons become significant? For which pivot selection strategy does the difference in the number of comparisons become significant? Compare your analysis with the actual running times and counter as a function of the input size n = 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, 8192, 16384 <time.h> and clock() function.). For comparison, you need to create two tables for execution times and a counter for both algorithms.2.
