Explanation / Answer

Dear... Here is the code that will give complete factorial code alongwith recursivive factorial function: comb: sub$sp, $sp, 16 sw$ra, 0($sp) sw$s0, 4($sp) sw$a0, 8($sp) sw$a1, 12($sp) jal fact move$s0, $v0 lw$a0, 12($sp) jalfact div$s0, $s0, $v0 lw$a0, 8($sp) lw$a1, 12($sp) sub$a0, $a0, $a1 jalfact div$s0, $s0, $v0 move$v0, $s0 lw$ra, 0($sp) lw$s0, 4($sp) addi$sp, $sp, 16 jr$ra #fact(n)
jalfact
move $s0, $v0 Hope this will help you...
