- Vectors store a linear arrangement of values, accessed by a single index. Two-dimensional arrays store a tabular arrangement of values, accessed by two indexes, for example matrix[i][j], where i is the row index, and j is the column index. A common two-dimensional array that you should have seen early on in your education is a multiplication table. For example, here is the multiplication table up to 5 x 5: 1 2 3 4 5 1 1 2 3 4 5 2 2 4 6 8 10 3 3 6 9 12 15 4 4 8 12 16 20 5 5 10 15 20 25 Write a program that asks the user for the number of rows and columns for a multiplication table and prints out the corresponding results.Implement the page replacement algorithm a) LIFO B) FIFO Reference string = 9 1 0 4 0 2 0 8 2 3 1 3 1 2 9 4 7 8 9 12 Calculate page fault ratio.

- you need to design, analyze, and implement algorithms to read in a sequence of characters from standard input and maintain the characters in a linked list with no duplicates. When you read in a previously unseen character, insert it at the front of the list. When you read in a duplicate character, delete it from the list and reinsert it at the beginning. The program implements the well-known move-to-front strategy which is useful for caching, data compression, and many other applications where items that have been recently accessed are more likely to be re-accessed. Requirements: The program should read a sequence of characters. The program should insert unseen character at the front of the list. The program should check if the character is not in the list to be inserted at the front of the list. The program should delete a duplicate character and delete it from the list and insert it at the beginning of the list. The program should check if the character is already in the list and…ONE X Intrd X O ssd ( X O Task: X Z Zote x O Diffe x G Uset x • Ident X ملفات البريد M i Fiver x C Get x + A elearning.utm.my/21221/pluginfile.php/318427/mod_resource/content/2/Module%205%20-%20Central%20Processing%20Unit%20AA24Apr2021-StudentPar.

- Please DO NOT respond to this question by copy/pasting the code provided elsewhere on the site, none of those work. Thanks. Virtual Memory Lab This lab project addresses the implementation of page-replacement algorithms in a demand-paging system. Each process in a demand-paging system has a page table that contains a list of entries. For each logical page of the process, there is an entry in the table that indicates if the page is in memory. If the page is in memory, the memory frame number that page is resident in is indicated. Also, for each page, the time at which the page has arrived in memory, the time at which it has been last referenced, and the number of times the page has been referenced since the page arrived in memory are maintained. The page table data structure is a simple array of page-table entries (PTEs). Each PTE contains five fields as defined below: struct PTE { int is_valid; int frame_number; int arrival_timestamp; int…Student information is being held in a data area, where each student record has the following format: The first nine bytes are the student number, held in ASCII The next byte is the course mark The next word is the section identifier There are well over three hundred such student records that have been loaded sequentially into memory starting at address $10000. The last record loaded is a dummy record with a section identifier of $FFFF, to show the end of the records.
