Question
Add comments to the following MIPS code and describe in a sentence or two what it computes. Assume that $a0 is used for the input and initially contains n, a positive integer.
Assume that $v0 is used for returning the output value.
begin: addi $t0, $zero, 0
addi $t1, $zero, 1
loop: slt $t2, $a0, $t1
bne $t2, $zero, finish
add $t0, $t0, $t1
addi $t1, $t1, 2
j loop
finish: add $v0, $t0, $zero
Explanation / Answer
Result $v0 is the sum of the odd positive integers 1 + 3 + 5 +
