Write an LEGv$8$ assembly function to compute $=($n$=1$ to a$)(+)^(1)$ using only one

loop. The inputs a and b to the function are passed using registers X$1$ and X$2$

respectively and the result y is stored or returned using register X$0.$ The inputs are

signed $64-$bit non$-$zero positive integers less than nine $(9).$ Assume all the registers

are used by the caller to store some data before calling the function and comment
