Answer the following:

A) Explain what is wrong with the given code. Describe the fault precisely by proposing a modification to the code.

B) If possible, give a test case that does not execute the fault. If not, briefly explain why not.

C) If possible, give a test case that executes the fault, but does not result in an error state. If not, briefly explain why not.

D) If possible give a test case that results in an error, but not a failure. If not, briefly explain why not. Hint: Dont forget about the program counter.

E) For the given test case (that results in a failure) below, describe the first error state. Be sure to describe the complete state. Hint: Dont forget about the program counter.

Test case: numbers = [1, 2, 3, 1];
