Write two MIPS procedures (mars) for the two C functions below: sum2 returns the sum of two integer arguments, and sum3 returns the sum of three integer arguments. For simplicity, crete a stack-frame only when needed. You can use MIPS pseudo-instructions.

int sum3(int a, int b, intc){

return sum2(sum2(a, b), c);

}

int sum2(int x, int y){

return x+y;

}
