Given a properly prepared String array containing five elements,which range
of results could a proper invocation of Arrays.binarySearch() produce?

Ans. -6 through 4

Why is the answer -6.According to me the last insertion point shoule be -5 by the formula
-(insertion point )- 1.
Since the last index must be 4 it becomes -4-1=-5

Correct me if i m wrong
