Please explain the steps

2. (7 points) A. (5 points) Write an assembly program to calculate the factorial of an unsigned integer n (n!) You need to prompt the user to enter an unsigned integer: Enter unsigned integer (n!): Pass the entered number to the Factorial subroutine. The calculated n! needs to be displayed on console screen from main subroutine. See the book page 305-306 where you will find main and factorial subroutines. Make the required changes and run the program Run your program using the debugger to verify your answers. - Use Step Into instead of Step Over to keep track of the stack, ESP, EBP, EIP during debugging the value of ESP from the register window and past it in the search To access the stack memory, copy text box in the memory window
