The function factorial() in Figure 9-1 was compiled to the code in Figure 9-2. Draw the status of stack and execution status as detailed as possible when executing factorial(2)( See Next Page). Assume that $sp contains 0x1038 when jumped to factorial() from main(). Fill in Figure 9-3(A) with stack status when 0xA0 jr $ra is executed and fill in Figure 9-3 (B) with stack status when 0xBC jr $ra is executed.
