Consider the following MIPS code: LOOP: slt $t2, $zero, $t1 beq $t2, $zero, DONE addi $t1, $t1, -1 addi $s2, $s2, 2 j LOOP DONE: a) Assume that register $t1 is initialized to the value 7 (in base 10), and $s2 is initialized to zero. What is the value of $s2 after executing the code segment above? b) Convert the MIPS instructions above to C code. Assume that registers $s2 and $t1 contain the variables B and i, respectively. c) How many MIPS instructions would be executed if the register $t1 was initialized to the value N?
