Provide the answers in the text box below the question. Consider the code segment below assuming that the variables x, y and z are integer values. Given values for the variables x,y and z, the code segment correctly determines whether x,y and z are all equal, whether onlyx andy are equal, whether onlyx and z are equal, whether onlyy and z are equal or whether x,y and z are all different. Code Segment: 1. if (x == y && y == z) 2. System.out.println("x,y and zequal"); 3. else if (x ==y) 4. System.out.println("only x and y are equal"); 5. else if (x == z) 6. System.out.println("only x and z are equal"); 7. else if (y == z) 8. System.out.println("only y and z are equal"); 9. else 10. System.out.println("x,y and z are all different"); (A) Show that this code segment is suboptimal by giving a set of values for the variables x, yandz that causes a relational expression in the code segment to be evaluated unnecessarily. Use integer values between-5 and 5 for the set of values.
