MIPS Printing issue

Question

I'm trying to get the user input (input=$v0) and then compare it to 10 (10=$t1). If the input is less than ten, I want to print '<'. If the input is greater than ten, I want it to print '>'. I've tried a few different things but for some reason it ends up printing both '<' and '>'. As well as an error reading "program is finished running (dropped off bottom)" Could anyone tell me what it is that I'm doing wrong?

    #where values are initialized
    addi $t1, $zero, 10 #number for comparison
    addi $t1, $zero, 60 #< less than 
    addi $t2, $zero, 62 #> greater than

    #Where things happen
    addi $v0, $zero, 5  # syscall 5 is to read integer syscall
    syscall             #get input from keyboard
    blt $v0, $t1, less  #go to less if less than 10
    bgt $v0, $t1, great #go to great if greater than 10

less:   #if input is less than 10
    addi $v0, $zero, 11 #print
    add $a0, $t1, $zero #copy $v0 to print
    syscall             #call for print 

great:  #if input is greater than 10
    addi $v0, $zero, 11 #print
    add $a0, $t2, $zero #copy $v1 to print
    syscall         #call for print

You need to finish your program somehow. If, for example, the code jumps to the less: lable, since you don't have any returns or a jump to a routine that finishes the program, the execution just continues straight down the great: part.

So you should make another lable end: where you exit from the program. And you should jump to the end: after executing the syscalls in less: and great: .

#where values are initialized
    addi $t1, $zero, 10 #number for comparison
    addi $t1, $zero, 60 #< less than 
    addi $t2, $zero, 62 #> greater than

    #Where things happen
    addi $v0, $zero, 5  # syscall 5 is to read integer syscall
    syscall             #get input from keyboard
    blt $v0, $t1, less  #go to less if less than 10
    bgt $v0, $t1, great #go to great if greater than 10
    #jump to end: (since there can also be an equal case)

less:   #if input is less than 10
    addi $v0, $zero, 11 #print
    add $a0, $t1, $zero #copy $v0 to print
    syscall             #call for print 
    #jump to end:

great:  #if input is greater than 10
    addi $v0, $zero, 11 #print
    add $a0, $t2, $zero #copy $v1 to print
    syscall         #call for print
    #jump to end:

end:
   #program exiting routine

I'm not sure about the exact syntax for the exiting routine, but I'm sure you'll have no problem figuring that out :)

Hope this helps!
