Suppose that you are working with a CISC machine using a 2.5 GHz clock (i.e., the clock ticks 2.5 billion times per second). This particular computer uses MASM-like instructions with the following timings: ADD reg, mem ; 7 clock cycles (i.e., the ADD micro-program has 7 instructions) ADD reg, immed ; 4 clock cycles LOOP _LabelName; 6 clock cycles Suppose that the following code fragment is used to sum elements of a numeric array. For this problem, assume that memory limitations are non-existent and that there is no limit to the size of the array. MOV BX, 0 MOV ECX, MAX SIZE MOV ESI, OFFSET list _ProcessArray: ADD BX, [ESI] ESI, 2 ADD LOOP ProcessArray ;initialize sum ;initialize LOOP counter ;initialize array pointer ; Add current list element ; Move array pointer to next element ; auto-decrement ECX, jump to more if ECX = 0 After initialization, how many array elements can be processed in 3.1 millisecond (ms)? Round your answer to the nearest integer. Note that 1 ms = 0.001 second.

Overview In this assignment, you will gain more practice with designing a program. Specifically, you will create pseudocode for a higher/lower game. This will give you practice designing a more complex program and allow you to see more of the benefits that designing before coding can offer. The higher/lower game will combine different programming constructs that you have been learning about, such as input and output, decision branching, and a loop. Higher/Lower Game DescriptionYour friend Maria has come to you and said that she has been playing the higher/lower game with her three-year-old daughter Bella. Maria tells Bella that she is thinking of a number between 1 and 10, and then Bella tries to guess the number. When Bella guesses a number, Maria tells her whether the number she is thinking of is higher or lower or if Bella guessed it. The game continues until Bella guesses the right number. As much as Maria likes playing the game with Bella, Bella is very excited to play the game…
JAVA PROGRAM Introduction The goal of this project is to develop a nontrivial computer program in the Java language by applying elementary programming language concepts learned so far. Specifically, the concepts to be used for this project include simple input/output, selection, iteration (loops), and possibly one-dimensional arrays (although the use of arrays is not required for completing this project). Developing a Java program for printing a calendar Statement of Problem: Develop a Java program to print a calendar for the year that the user will provide as an input to the program. Use the Eclipse IDE (on a Windows or Mac machine). Your program must fulfill the following requirements: Your program should prompt and receive as input an integer value representing the year for which the user wishes to have a calendar printed. This integer must be in the range from 1780 through 2040. In case the user input a year that is outside this range, your program must print out a message such as…

Question 1: Please develop a program. The program shows a O(n^2) time complexity. You may design nested loops. When you input a number, the output should be how many times of the loops. For example, if your input is 10, the number of loops should be 100 times, 200 times, 300 times, etc. The number of loops do not have to be an accurate number. Question 2: Please develop a program. The program shows a O(nlgn) time complexity. You may design nested loops. When you input a number, the output should be how many times of the loops. For example, if your input is 10, the number of loops should be 30 times, 60 times, etc. The number of loops do not have to be an accurate number.

The code box below defines a variable route as a list of directions to navigate a maze. Each instruction is one of the following four basic commands: higher move one step in the positive y direction • lower. move one step in the negative y direction • left: move one step in the negative x direction • right: move one step in the positive x direction Define a function step that takes two arguments, a location (as a tuple of x and y coordinates) and an instruction (higher, lower, left, right) as a string. Given the provided location, it should return the new location (as a tuple of x and y coordinates) when following the specified instruction. If the instruction is invalid, the old location should be returned. Use the function step to determine the final position when starting from the point (0, -4) and following all instructions in the list route. Assign this final position to the variable final_point.
Exercise 2 - Primer on Loop Referring to the code for drawing an equilateral triangle provided to you earlier in this prac sheet, you may have noticed that, in order to draw the triangle, we are repeating a set of two commands three times i.e. robot.forward( 100) followed by robotright(120). Python (and many other programming languages) provide us a tool called a "Loop" to repeat a certain set of steps a certain number of times. As usual, in order to use loops, we have learn the correct Python syntax for it. The following Python code uses a loop to draw the same equilateral triangle as the code provided earlier: import turtle wn - turtle.Screen() wn.bgcolor("white" robot - turtle. Turtle() robot. setheading(90) robot shape("turtle") robot.colort"green" robot. pensize(3) for i in range(3): robot. forward( 100) robot. right(120) wn.exitonclick() Note that the lines that fall under the line that starts with "for" have to be indented; this means that you have to insert spaces or tabs (USE…
Code in python: A certain company has encoded the accounts of its customers and requires that you provide an algorithm that, given an account code, informs if it is valid according to the following description: The account codes are made up of 4 digits counted from right to left, plus the verification digit. The verifying digit is obtained by adding the digits of the account number of the even positions and multiplying the digits of the odd positions, from the new result the residue of the division is extracted for 10, which represents the verifying digit. Develop the code in python as a check digit class that returns 1 if it is correct or 0 if not Heading: Extract digits, verifier calculation, Account verification, Integral algorithm
