Assume the first instruction starts at memory address 4000: slt $tl, $s2, $s3 beq $t1, $s4, foo beg s81, szero, boo j Exit foo: add $s0, $s1, $s2 j Exit boo: addi $s4, $s5, 2 Exit: Convert all beq and j lines from the code above into machine code: a. beq $tl, $s4, foo b. beq $sl, $zero, boo c. j Exit (first) d. j Exit (second)
