Quicksort's partition function might be modified as follows: Count the amount of values that are strictly fewer than the leftmost value to determine where the leftmost value should go. The final figure is the precise index for the required value. The value at the indexed position should be swapped out with the value on the left. Does this provide an accurate quicksort with the remaining code in place? If not, please explain.

Problem Description: Write a telephone lookup program. Read a data set of 1,000 names and telephone numbers from a file that contains the numbers in random order. Handle lookups by name and also reverse lookups by phone number. Use a binary search for both lookups.
Write a program that allows the user to sort using the Heap Sort and Bin/Radix Sort. The program should be able to read in data from a binary file. The first element of the binary file will be used to tell how many elements to read in. Once all the data has been read in, the program should sort the data. The user should be able to choose which algorithm to use to sort the data. The program should print the time before and after the sort. The last part of the program should prompt the user for a lower and upper bound. These two values should then be used to decide how much and which part of the array will be display. Note: The binary files may have duplicate numbers in them. Make sure your sorts are able to handle these cases. Reminder: Bin sort must be constructed yourself using pointers. No vectors, queues, etc..

3. lookup_friends_heights This function takes a friends database (a list of dictionaries, like the previous functions) and a list of friends names, and it returns a list of heights for the specified friends. If a given friend's name is not present in the friends database, we put a None in the corresponding slot. We assume that there will be at most one friend with a given name in the list. You may want to use nested for-loops for this function. Sample calls should look like this. >>> lookup_friends_heights([{"name":"todd","height":170},{"name": "sarah", "height":165},{"name":"dweezil", "height":175}], ["dweezil", "sarah"]) [175, 165] >>> lookup_friends_heights([{"name": "todd","height":170},{"name": "sarah","height":165},{"name": "dweezil", "height":175}], %3D ["sarah", "elíza", "dweezil"]) [165, None, 175]

The purpose of this project is to assess your ability to: Implement a hash table Utilize a hash table to efficiently locate data Analyze and compare algorithms for efficiency using Big-O notation For this project, you will implement a hash table and use it to store words in a large text file. Your hash table should use chaining for collision resolution. You may design any hash function you wish. Your program will read a file and insert each word into a hash table. Once the table is populated, allow the user to enter words to search for. For each word entered, your program should report the number of elements inspected and whether or not the word was located. Provide an analysis of your insert and search algorithms using Big-O notation. Be sure to provide justification for your claims.

C# Scenario: You have a collection of 100 RANDOMIZED integers. Your program has a method called Find, which has one parameter, an integer value to search for. Of the options below, what would be the best strategy to maintain efficiency? 1. Binary Sort 2. Linear Search 3. Sort the Data using a Merge Sort, then use Binary Search
(You may use any of the following: Decision, Merge, Fork, Join, Action, Object and any other nodes. The more the better. :) (i) You have green, red and blue marbles in a single box. The marbles are sorted in the following way by color. One marble is picked at a time from this box, the color of the marble is checked and placed in a green box if it is green, blue box if it is blue and red box if it is red. This process continues until all marbles have been placed in the respective boxes. The marbles are picked in sequence one after another. ***After this step, the marbles in each box are counted and each box is labeled with the color and count. This task is done in parallel for each of the boxes. **** The three boxes are then placed in the garage. Assume placing the sorted boxes in the garage is a single task. (Note, the counting is NOT done while sorting the colors). (ii) Modify the counting to happen while picking each color marble from the single box and provide a different version…
However, the number of integers must be a power of 2. In main.c, key[ ] has 16 integers. But as you should alreadyknow, the program will not sort if one integers is removed or added. What you are going to do is modify the mergesort.c module so that a non-power of 2 number of integers can be sorted. When you modify a module, indicate by way of comment, what was changed, the date the change was made. You will also need to add or remove an integer to/from key[] in module sort158a.c.You are NOT allowed to change merge.c, mergesort.h or wrt.c filesThe mergesort function in file mergesort.c MUST call the merge function which it currently does.The main function in sort158a.c you can only change the number of integers in the key[] arrayBelow are 3 examples of output. The first with an array of 15 integers. The second with an array of 16 (power of 2) integers and the third with 17 integers.Example of Output with 15 integersBefore mergesort: 4 3 1 67 55 4 -5 37 7 4 2 9 1 -1 6After mergesort: -5…
PYTHON QUESTION This assignment requires you to create a dictionary by reading the text file created for the Chapter 6 assignment. The dictionary should have player names for the keys. The value for each key must be a two-element list holding the player's goals and assists, respectively. See page 472! Start with an empty dictionary. Then, use a loop to cycle through the text file and add key-value pairs to the dictionary. Close the text file and process the dictionary to print the stats and determine the top scorer as before. In fact, much of the code used in program6_2.py can be copied and used for this program. Printing the stats for each player is the most challenging part of this program. To master this, refer to the examples in the zip file that can be downloaded from the "Dictionary values can be lists" link in the "Learn Here" part of this module. NOTE: you do not need to submit the text file. Submit just this program. The required output should be the same well-formatted table…
