3. Implement the following MIPS pseudo-instructions (those instructions without an instruction format) with generic MIPS instructions (those instruction with an instruction format definition, e.g., R-type, I-type or J-type)

(a) li $a0, 10

(b) not $t0, $t1

(c) bge $s1, $s2, label

(d) seq $t1, $t2, $t3
