3. Given the following MIPS Assembly program. What are the values of registers Stl and St2 after running the program? What is the value at memory location unitX after running the program? .data unitX: initA word-20 30-40 50 0-60 80 word ? .text la St0, initA li Stl, 0 loop: lw $t2, 0(St0) beqz $t2, done add Stl, St1, $t2 addi $t0, St0, 4 b loop done: sw Stl, unitX(S0)
