Write a MIPS assembly language program to calculate n! where n is 0=

here is what i have so far:

.data

str: .asciiz "Enter a number between 0 and 10 to calculate the factorial: " str2: .asciiz "The factorial of " str3: .asciiz " is:" new: .asciiz " " error: .asciiz "ERROR: NUMBER HAS TO BE BETWEEN 0 AND 10" error2: .asciiz "ERROR: NUMBER HAS TO POSITIVE"

.text

main:

li $v0, 4 la $a0, str syscall

li $v0, 5 syscall

add $s1, $v0, $0

li $s2, 10

blt $s1, $0, nonPos bgt $s1, $s2, between

li $t1, 1

li $v0, 10 syscall

loop: beq $s1, $,

j loop

done:

li $v0, 4 la $a0, new syscall

la $a0, str2 syscall

li $v0, 1 add $a0, $s1, $0 syscall

la $a0, str3 syscall

nonPos: li $v0, 4 la $a0, error2 syscall

la $a0, new syscall

j main

between: li $v0, 4 li $a0, new syscall

la $a0, error syscall

j main
