Write a mips assembly language program that a. prompts the user for a zip code (as a 5-digits unsigned integer, or 0) with the string "give me your zip code (0 to stop): ". no error checking is necessary, assuming that the user will give correct numbers. b. if the input is 0 stops c. otherwise, calculates the sum of all digits, then print out the result with the leading string "the sum of all digits in your zip code is: " d. repeats from a. for example, if the user gave the input 75081 the program will print out "the sum of all digits in your zip code is: 21"// the section above has already been answered, use this to do the bold section below. rewrite the mips program in hw#3 to perform the same function, but implement the task of calculating the sum of digits as a function (subroutine). implement two version of this functions, one is iterative and the other is recursive. the main program should call each of these two functions to calculate and display the sum after the user has input a zip code.
