The Program:

Public int findMyLast (int[] x, int y) {

For (int i=x.length-1; i>0; i--) {

If (x[i]==y) {return I;}

}

Return -1;

}

Test Cases:

Case 1: x = [2, 3, 5], y=2;

Expect: findMyLast(x,y)==0

Case 2: x=[2, 3, 5, 2], y=2;

Expect: findMyLast(x,y)==3

Questions:

1. For the given test case test1, identify the first error state. Be sure to describe the complete state.

2. Please use the RIPR model to arrive at a test case where a fault being revealed.
