Given a singly linked list L, where x and y are two data elements that occupy the nodes NODEX and NODEY with PREVIOUSX as the node, which is the previous node of NODEX, write a pseudo-code to swap the date x and y in list L by manipulating the links only (data swapping is not allowed). Assume that x and y are available in the list and are neither neighbors nor the end nodes of list L. For example, given the list L shown in Figure P6.10(a), with L, NODEX, NODEY and PREVIOUSX marked on it, the swapping should yield the list shown in Figure P6.10(b). NODEX and NODEY are neither immediate neighbors nor the end nodes of list L.

The program is to be written in C language and only one array is to be used. The input is to be given during compile time. The question is in the image.
Recursion and loops. Provide both recurrent and loop based implementation of the function count( e, L ) that returns the number of es in L, where L is a list. Also consider cases when L is an empty list. Create test cases and run driver, show how function runs in spyder (py file) or ipynb file. Submit code as a py or html or pdf files with screenshots of the runs.

Implement a STUDENT RECORD program in C++ (SINGLY LINKED LIST) that does the following: 1. Displays a Menu (do..while loop) with choices for user to choose from (similar to the one shown below) MENU • • Add a student to the record. Remove a student from the record. Display the whole record list. Modify the student record. Exit. 2. Enables the user to choose the choice of action by typing the number between (1 to 5): adding a student to the record. removing a student from the record. displaying the whole record; 4) modify the student record. exit. The record contains students' full name, student number, and general weighted average. 3. The list must display proper messages (when the list is full, or when the list is empty, or when the items requested to be deleted is not in the list, etc.) 4. The program should run until user chooses to Exit. NOTE: - All the code must be well commented per line - Must be a singly linked list - Use dynamic memory allocation - Use an array Has the…

dont write code. just write algorithm or related theory of the following question. Narrative 2: We need to have a generic module which reads in file and gives the output in the format which would facilitate other programs to do comparison like the one we saw above to carry out analysis and comparison. Response Required: Write a program that reads a given text, outputs the text as is, and also prints the number of lines and the number of times each letter appears in the text. An uppercase letter and a lowercase letter are treated as being the same; that is, they are tallied together. Since there are 26 letters, we use an array of 26 components to perform the letter count. We also need a variable to store the line count. The text is stored in a file, which we will call textin.txt. The output will be stored in a file, which we will call textout.txt Input: A file containing the text to be processed. Output: A file containing the text, number of lines, and the number of times a letter…
Using PYTHON: Create a python program that supplies the missing traversal from the user input. Ask the user for INORDER and let them choose whether to use postorder or preorder. For example, if they chose POSTORDER, then they must supply the nodes of INORDER and POSTORDER and let the program identify the PREORDER. The images below are what is expected to be printed out:
In Python the only import that may be used is Numpy Implement a function called page_rank which will take as input a numpy array M, which will represent the transition matrix of a directed graph, and a positive integer n. The output will be a numpy array which gives the page ranks of each vertex in the graph represented by M. You will iterate the update process n times.
