Can anyone help with a MARIE simulator program, please

THIS IS NOT A C++. thank you

Write MARIE assembly language programs that do the following: 1. Write a program that inputs four integers, il, i2, i3, and i4 in that order. It computes the following: (il i2) + (i3 - i4) The result should be written to output, You are required to write a procedure that computes the expression shown above. The procedure should not do input or output 2. Write a program that inputs integers, x, y, and z. It outputs the difference of the largest and first element entered. You may assume x, y, and z all have different values. So if 8, 12, and 9 are input, the output would be 4 (12-8 since 12 is the largest and 8 is the first). 3. Write a program that inputs an integer and prints to output a countdown from the integer to 0. For example, if 7 is input: 7 6 2 0 Comment each line in the code for all programs. Class 1 The .mas file for each program needs to be placed in the Homework 10 Assignment on Blackboard. The icon for the.ma 5 points extra credit for each problem that you have the shortest correctly working code in the class (counting code and reserved memory words)
