Q2) Assume that the stack is empty and that the stack pointer is at Ox1000 8020. Assume that function inputs are passed using registers $20-$a3 and return value must be put in register $v0. Put the final value of b in $so. a.) Write the MIPS code for the C/JAVA code below. If you use any saved registers, save them to stack. Main... { int b = func(1, 3); } int func(int a, int pow){ if (pow > 1) return a*func(a,pow-1); else return a; }
