b) Consider the following MIPS loop: LOOP: slt St2, $ 0, $t1 Beg $t2, $0, DONE subi $t1, $t1, 2 addi $s2, $s2, 2 LOOP DONE: 1. Assume that the register $t1is initialized to the value 20. What is the value in register $s2 assuming $s2is initially zero? 2. For each of the loops above, write the equivalent C code routine. Assume that the registers $31, $s2, $t1, and $t2 are integers A, B, i, and temp, respectively. 3. For the loops written in MIPS assembly above, assume that the register $t1 is initialized to the value N. How many MIPS instructions are executed
