Explanation of Solution
Difference between sequential access and random access:
| Sequential access | Random Access |
|
Files are processed in sequential order. |
Files are processed in random order. |
|
If the records are needed to be accessed in sequential order, sequential file access is used. |
If the files are needed to access in random order, random file access technique is much faster. |
|
In sequential access, the file pointer moves only in one direction... |

A common memory matching game played by young children is to start with a deck of cards that contain identical pairs. For example, given six cards in the deck, two might be labeled 1, two labeled 2, and two labeled 3. The cards are shuffled and placed face down on the table. A player then selects two cards that are face down, turns them face up, and if the cards match, they are left face up. If the two cards do not match, they are returned to their original face down position. The game continues until all cards are face up. Write a program that plays the memory matching game. Use 16 cards that are laid out in a 4 4 square and are labeled with pairs of numbers from 1 to 8. Your program should allow the player to specify the cards that he or she would like to select through a coordinate system. For example, in the following layout: 1 2 3 4 1 8 * * * 2 * * * * 3 * 8 * * 4 * * * * all of the face down cards are indicated by *. The pairs of 8 that are face up are at coordinates (1,1) and…
When an author produces an index for his or her book, the first step in this process is to decide which words should go into the index; the second is to produce a list of the pages where each word occurs. Instead of trying to choose words out of our heads, we decided to let the computer produce a list of all the unique words used in the manuscript and their frequency of occurrence. We could then go over the list and choose which words to put into the index.
The main object in this problem is a "word" with associated frequency. The tentative definition of "word" here is a string of alphanumeric characters between markers where markers are white space and all punctuation marks; anything non-alphanumeric stops the reading. If we skip all un-allowed characters before getting the string, we should have exactly what we want. Ignoring words of fewer than three letters will remove from consideration such as "a", "is", "to", "do", and "by" that do not belong in an index.

- Assignment for Computer Architecture You are to write a program in MIPS that computes N! using recursion. Remember N! is the product of all the numbers from 1 to N inclusive, that is 1 x 2 x 3 x (N – 1) x N. It is defined as 1 for N = 0 and is undefined for values less than 0. The programs first requests the user to input the value of N (display a prompt first so the user knows what to do). If the input value is less than 0, the program is to display “N! undefined for values less than 0” and then requests the user to input the value of N again. If the value input is non-negative, it is to compute N! using a recursive function, that is one that calls itself. You are to have your name, the assignment number, and a brief description of the program in comments at the top of your program. Since this is an assembly language program, I expect to see comments on almost every line of code in the program.

- Crossover and Mutation The two main operations in evolutionary computing are crossover and mutation. Crossover works like this: Randomly choose two parents from the population. Let’s say these: Parent 1: T F T F T T F Parent 2: T T T F F T T Those two parents will create a child whose DNA is related to the parents’. It works like this: for each of the seven genes in the chromosome, we will randomly pick a number between 1 and 10 and use it to choose which parents’ value the child will get. If the random number is 1 through 5, we will use Parent 1’s included value for the child; if it is 6…arrow_forwardCrossover and Mutation The two main operations in evolutionary computing are crossover and mutation.

- Define the term " recursion limitations " .arrow_forwardArtificial Intelligence (Part - 2) ==================== The Towers of Hanoi is a famous problem for studying recursion incomputer science and searching in artificial intelligence. We start with N discs of varying sizes on a peg (stacked in order according to size), and two empty pegs. We are allowed to move a disc from one peg to another, but we are never allowed to move a larger disc on top of a smaller disc. The goal is to move all the discs to the rightmost peg (see figure). To solve the problem by using search methods, we need first formulate the problem. Supposing there are K pegs and N disk.

The puzzle solver must fill in the squares with the digits 1 to 9 such that no digit is repeated in any row, any column, or any of the nine 3 by 3 subgroups of squares. Initially, some squares are filled in already and cannot be changed. For example, the following might be a starting configuration for a Sudoku puzzle: Create a class SudokuPuzzle.java Download SudokuPuzzle.java that has the attributes • board—a 9 by 9 array of integers that represents the current state of the puzzle, where 0 indicates a blank square • start—a 9 by 9 array of boolean values that indicates which squares in board are given values that cannot be changed and the following methods: • SudokuPuzzle—a constructor that creates an empty puzzle • toString—returns a string representation of the puzzle that can be printed • addInitial(row, col, value)—sets the given square to the given value as an…arrow_forward
