Question

Hello, I'm having trouble completing this program in less than four lines using MIPS programming language, we are required to fill in the missing code as indicated (via comments).

IMPORTANT: As indicated in the program's comments:

⇒

Write no more than certain number of lines of code as indicated. (One instruction per line, and there will be penalty if your code consumes more lines.)

⇒

Code MUST use only instructions that are allowed i.e., only bit manipulating instructions: (ANDing, ORing, XORing,NORing and shifting).

⇒

MUST NOT in any way change the lines of code already written. ############################ # prompt user to enter an integer in the range [0, 63], read the integer, # and display if the integer is of type 0 ( <= 31 ) or 1 ( > 31 ) ############################ data segment ################################            .data typeLeg:       .asciiz "1 for <=31, 0 for >31\n" inputProm:       .asciiz "Enter integer between 0 and 63 (inclusive): " outputLab:       .asciiz "Integer entered is of type " ############################ code segment ################################            .text            .globl main main:            li $v0, 4            la $a0, typeLeg            syscall           # print type legend            la $a0, inputProm            syscall           # print input prompt            li $v0, 5            syscall           # read integer            move $v1, $v0       # save integer read in $v1            li $v0, 11            li $a0, '\n'            li $v0, 4            la $a0, outputLab            syscall           # print output label            li $v0, 1            ##########################################################            # Insert below NO MORE THAN 4 lines of code that involve ONLY            # bit manipulating instructions (ANDing, ORing, XORing,            # NORing and shifting - only whatever that are needed)            # so that the program will work just like the sample runs            # shown at the bottom (some blank lines edited out).            # HINT: Risking telling the obvious, the instructions you            # insert are to cause the content of $a0 to become            # the desive value (1 or 0) when printed as integer.            # You MUST test your completed program for AT LEAST the            # test cases shown (and include the result in hardcopy).            ##########################################################                                 #Your Code Here                                             syscall           # display desired output               ##########################################################               li $v0, 10       # exit gracefully    syscall            ########################## test cases ############################## # 1 for <=31, 0 for >31 # Enter integer between 0 and 63 (inclusive): 0 # Integer entered is of type 1 # -- program is finished running -- # # Reset: reset completed. # # 1 for <=31, 0 for >31 # Enter integer between 0 and 63 (inclusive): 31 # Integer entered is of type 1 # -- program is finished running -- # # Reset: reset completed. # # 1 for <=31, 0 for >31 # Enter integer between 0 and 63 (inclusive): 32 # Integer entered is of type 0 # -- program is finished running -- # # Reset: reset completed.
