Explanation of Solution

Difference between sequential access and random access:

Sequential accessRandom 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…
sum= 0; for (int i = 0; i 1) { sum++; i= 1/2; } = 2*log2 (n) We denote by Ta(n), Tb (n), Te(n) the running time of the three fragments. 1. Give evaluations for Ta(n), Tb (n), Te(n). 2. Is T(n) = O(Ta(n)) ? Answer YES or NO and justify your answer. 3. Is Te(n) = (Ta(n)) ? Answer YES or NO and justify your answer.
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. Also make the code neat: line up the command fields, the register fields, and the comment…
