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 19

Using binary search approach, write a python function named update_record, which takes the following inputs: 1: students_records – Nested List of Tuples. Each tuple of the list represents student's data. 2: ID – An ID of a student whose data has to be updated 3: record_title – type of data that has to be updated 4: data – A new data that should replace record_title data and update the record of students' data associated to specific ID. If ID is given as the data to be updated, then return a message that ID cannot be updated. If ID is not found in students_records, then return a message that Record not found. NOTE: The type of record_title input can be "ID", "Email", "Mid1" or "Mid2". Please use the same spelling for these types in your code, because the same have been used in test cases. Test cases are attached below: student_records = '[("aa02822", "ea02822", 80, 65),("ea02822", "ea02822@st.habib.edu.pk", 80, 65),("fa08877", "fa08877@st.habib.edu.pk", 66, 67),("gh04588",…

Assume 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].

Use C++ Language. Solve ASAP, Kind Regards.

Subject - Design & Anal algorithms Please complete all the questions together.  Use python code. Thank you in Advance. You are given two sorted arrays, array A of size n and array B of size m. Write pseudo-code for the Merge procedure that merges arrays A and B into a new sorted array C. You can assume C has been preallocated to have the right size

Create two Arrays A with 10 unsorted integer elements and B with 10 unsorted floatelements. Find the largest element in A and B and then sum both of them calling afunction SumAB() by reference. Sort A and B and then call another function StichAB()to merge B with A. Be careful about memory leakage.

Algorithm 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. Revises the function quickSort so that it always chooses the last item in the array as the pivot. Add a counter to the function…
