Write a MIPS program to complete the following functions. You must write comments and follow the register convention. (1) Declare an integer array of 20 elements and other variables and labels; [5] (2) Write a procedure to initialize the array. Use random numbers between 0 and 99, and use a loop to initialize the array. [10] (3) Implement a sort procedure. You can use the sort procedure given in textbook 2.1.3. [5] (4) Write the main program. It calls the initialization procedure; prints the numbers in the array; calls the sort procedure to sort the numbers in the array; and print the numbers in the sorted array. [10] Based on the syscalls in MARS simulator, you can use the following code to generate random numbers between 0 and 99. li $a1,100 # define the upper range li $v0, 42 # 42 is the syscall code for random integer generation syscall # the generated random number will be placed in $a0.
