Indicate the MIPS assembly corresponding to the following C blocks of code.
You can assume that the values of variables x and y are stored in registers R1 and R2, respectively. (a)
if (x==1) then
x+=5; else
x+=20;
(b)
for (int x=0; x<20; x++) y=y-2;
For block of code (b), show two solutions: one using only conditional branches, and one using also an unconditional branch (or jump). [7 for solution #1 + 7 for solution #2]
