MIPS assembly program

Project Description: (a) Write and execute a MIPS assembly program that reads three input numbers, and outputs the numbers in the order of largest to smallest. (b) Write and execute a MIPS assembly program that performs the addition of all even numbers between 0 & n, and displays the result, where n is a user entered non-negative number. The program should prompt the user to enter a number n, and should stop if a negative number is entered. Your program should be well commented and efficient. They should produce the correct result after loading and running in the pcspim or xspim simulator. If possible in less than 12 hours would be very nice since i have to demonstrate
