. Factorial (Iterative algorithm)

• Get a user input of one non-negative integer numbers: A
• Calculate C is a factorial of A
• Print C

Test case: A=4

Output should be 24

• Implement the algorithm in C. The arithmetic operations are limited to only addition and subtraction.
• A screenshot of the final execution states for a test case of your C code. Note your program needs to be general to take any input values using input instructions. However, a test input is used just to create a screenshot.
• After implementing in C, Implement the algorithm for MARIE architecture
• A screenshot of the final execution states for a test case of your MARIE assembly code. Note your program needs to be general to take any input values using input instructions. However, a test input is used just to create a screenshot.
• Include the number of instructions in a list.
