would you like to give some help on clear up all the spaces in the user input

hi i need help for this .

Using MARIE, create a program that will accept as input the user's first name and output "Hello, [user's input]!"

Can you help me with this?

Write a MARIE program that accepts an integer from the user, and if it is a prime number the program will output 1, otherwise, the program will output 0.
Examples:
If the user input is 17, the output would be 1
If the user input is 2, the output would be 1
If the user input is 15, the output would be 0
If the user input is -2, the output would be 0

You should write and run the program using MARIE simulator. Add enough comments to understand your code.
You do not have to include the .mas file in the submission. Instead, the code should be presented as a word-processed section in the assignment, not as an image. Insert images to show you have tested the code with several possibilities.

Can you help me with the following question please. Urgent
MARIE program to calculate some basic statistics on a list of positive numbers. The program will ask users to input the numbers one by one. Assume that all numbers will be in the range 1 to 1000. To terminate the data entry, the user will input any negative number. Once the data entry is complete, the program will show four statistics about the list of numbers:

(i) Count, (ii) Minimum value, and (iii) Sum of the numbers.

As an example, if the user enters the following decimal numbers as input (one after the other)

23, 6, 78, 36, 3, 250, 127, 210, -5

the program would output the following values as the count, minimum and sum respectively:

8

3

733

Assume that the user will always provide valid numbers as input, that is, do not worry about dealing with invalid input data.

Write comments within your program so that a reader can understand it easily.

Can you please help me with this Marie program. Please it's urgent!

Write a MARIE program to allow the user to input 8 integers (positive, negative, or zero) and then find the smallest and the largest and print each of these out.

As an example, if the user enters the following decimal numbers as input (one after the other)

23, -6, 78, 0, 36, 3, -250, –5

the program would output the following values as the maximum and minimum, respectively:

78
-250

I have the solution, let me know if you still need it.

Hello, I really need your help now because I really don't know how to write the MARIE code.
Using the Marie Simulator found on the web site, you will create a small assembly language Marie program. The program is a VERY simple addition tool. Basically, your program will issue a prompt (">"), then accept a single digit integer from the user. (Hit the ENTER key to actually enter the value). It will then echo that integer to the screen, print a "+” symbol, then wait for a second digit. It will then echo this digit to the screen, followed by the "=" symbol and then the result of the addition. There is no error checking, so all numbers entered should be a single digit, and the result must also be a single digit. So 1+3=4 is okay, but 7+9=16 is not (i.e., your program is not expected to be able to handle the second case properly). When the calculation is finished, you must tell the program whether to continue or not. If you enter a "!", the program will print "BYE" to the screen and halt. If you simply hit the ENTER key instead, it will loop and provide a new prompt. Note that IO is quite limited on Marie so you can't do anything fancy. You should select the "no linefeed" option in the Output Window - everything will be printed on one line. A sample output for a two iteration loop would be something like this: > 3+2=5>1+2=3BYE You will hand in your source file with your submission. It should be called adder.mas. The tutor will assemble and run your source code.  

Can you please help me the code for question above? I can etransfer for you if need. I really need the code. Thank you so much

Please feel free to email me if you have any questions.

Hi can someone pls tell me the code for checking for palindrome using MARIE code ? The palindrome needs to be checked for the user input which I managed to create . So basically what I want to do is check for palindrome in the input I enter and if it is a palindrome output 1 . PLS PLS reply to this

Please feel free to email me if you have any questions.

where can I find your email ?

where can I find your email ?

It can be found on my GitHub

Hi, can someone help me with this question. I don't get how you can input in operations like "+, -, *" and use to get the sum of the numbers you already inputted.
Here are the questions:

1. Using the INPUT instruction wait for the user to enter an integer number.
   a. Be sure the dropdown for the Input field says Decimal
2. Using the INPUT instruction wait for the user to enter a second integer number.
   a. Be sure the dropdown for the Input field says Decimal
3. Using the INPUT instruction wait for the user to enter the character +, - or *.
   a. Be sure the dropdown for the Input field says ASCII. Then type the symbol for the operation you want, i.e. “+”, “-“, etc.
4. Perform the desired addition, subtraction or multiplication operation.
5. Store the result in a variable in memory.
6. Display the result via the OUTPUT instruction.

Thank you!

@areaknight99 Please read the other comments. I do not answer questions here but you can email me.
