Simulation: Write a MIPS program that computes the expression;
y = A * B + C * D Where A, B, C, and D are integers
Algorithm Analysis
Start with 102 coins on a table, 98 showing heads and 4 showing tails. There are two ways to
change the coins:
• flip over any ten coins, or
• place n+ 1 additional coins, all showing tails, on the table where n is the number of heads
currently showing on the table.
For example, you might begin by flipping nine heads and one tail, yielding 90 heads and 12 tails,
then add 91 tails, yielding 90 heads and 103 tails.
(a) Model this situation as a state machine, carefully defining the set of states, the start state, and
the possible state transitions.
(b) Optionally, explain how to reach a state with exactly one tail showing.
(c) Consider the following derived variables:
C ::= the number of coins on the table H ::= the number of heads on the table
T::= the number of tails on the table C, ::= parity (C)
H2 ::= parity(H)
T2 ::= parity(T)
Here the parity : Z → {0,1} function is defined as parity(n) = 0 when n is even and 1
otherwise.
Which of these variables is strictly…
A very known application in natural language processing is to extract information from a given text. In this lab, you will be able to extract some emotions (Sad and Happy) from a given string and calculate the score of each emotion. You will be given below the words that express sadness, anger, and happiness. For each word, you will be given weight as well, so that when you are calculating for example the score for sadness in the text (string), you can use this formula:

- Write a graphical program to trace a random walk (see previous two prob-lems) in two dimensions. In this simulation you should allow the step to be taken in any direction. You can generate a random direction as an angleoff of the x axis. angle = random() * 2 * math.piarrow_forwardPseudocode is a useful tool for mapping out complex algorithms in a language-independent way before even writing one line of code. GoogleStepwise Refinement and Divide-and-Conquer. We’re going to practice this approach in detail here. We’ll start with a very high level description of the program, and flesh out bits of detail in each stepwise refinement. Given the small amount of pseudocode below, can you take a small, incremental step to describe in more detail the steps required to accomplish this task? Pseudocode Refinement Step 1–The Problem Statement This should be as short as possible, yet convey the full requirement of the program (however vague). Consider the following starting point for your stepwise refinement, which was pulled from the homework description. “Given a target file to find and a starting directory, determine if and where the target file exists.” Pseudocode Refinement Step 2 Using the above sentence as an incomplete guide split the embedded concepts into 4…arrow_forwardWrite a complete processing program so that you can control a red ball on the screen using keyboard arrow keys: UP/DOWN: ball moves up/down; LEFT/RIGHT: ball moves left/right; when the ball hits border, it won't be able to move across the border is (stuck there instead). R/r key resets the ball back to center.arrow_forward
- JAVA LANGUAGE Sort It Yourself by CodeChum Admin A descending order means values arranged from largest to smallest. But in your case, you're going to have to sort these integers in ascending order, which means from smallest to largest. Instructions: Input three integers. Print the integers in ascending order using your knowledge on conditional statements. Input A line containing three integers separated by a space. 6·1·3 Output A line containing three integers separated by a space. 1·3·6arrow_forwardWrite a program using Python to solve the locker riddle which reads as follows: Imagine 100 lockers numbered 1 to 100 with 100 students lined up in front of those 100lockers:The first student opens every locker.The second student closes every 2nd locker.The 3rd student changes every 3rd locker; if it’s closed, she opens it; if it’s open, she closes it.The 4th student changes every fourth locker (e.g., 4th, 8th, etc.).The 5th student changes every 5th locker (e.g., 5th, 10th, etc.).That same pattern continues for all 100 students. Which lockers are left open after all 100 students have walked the rowof lockers?arrow_forwardIn number theory, a happy number is a number which eventually reaches 1 when replaced by the sum of the square of each digit. For instance, 13 is a happy number because 12 + 3? = 10 and 1² + o² = 1. On the other hand, 4 is not a happy number because the sequence starting with 4 = 16 and 12 + 62² = 37 and eventually reaches to 4 that is the number that started the sequence, and so the process continues in an infinite cycle without ever reaching 1.

A perfect number is the number that is numerically equal to the sum of its divisors.

On the other hand, 4 is not a happy number because the sequence starting with 4? = 16 and 12 + 6? = 37 and eventually reaches to 4 that is the number that started the sequence, and so the process continues in an infinite cycle without ever reaching 1.

- A robot starts on a point marked “A” on a rectangular grid of points. The starting point is always the top left point on the grid. The robot can move left, right, up or down, moving from one point to the next. By moving in steps going left, right, up or down, the robot would like to reach a point marked “B”, which is always the bottom right point in the grid. Sometimes, points are marked as “x”, and the robot is not allowed to visit them at all. A robot is never allowed to visit a point more than once. In how many ways can the robot move from A to B and visit all points along the way? For example, in the following grid, represented in text as A . . . . B there is only one path from A to B: In the following grid, represented in text as A . . x x B there is still only one path (we're lucky because of the two x's): However, in the grid A . . . x B there are no ways for the robot to move from A to B and visit all points that are not marked with “x”.

Your program should select a random number between 1 and 50 and then let the user try to guess it. The program should continue asking the user for a number until he guesses correctly. (See below for some tips on random numbers). CHALLENGE #1: Modify your program so that it only allows the user 10 guesses, and then declares them to be an inadequate guesser if they haven’t gotten it correct. Your program should output the random number chosen. CHALLENGE #2: Modify your program so that after they guess a number (or get declared inadequate, if you do Challenge #1) that it asks them if they want to play again, and responds accordingly.arrow_forward
