please answer

Consider the following method implementation public static int enigma (int x, int y, int z t return x y t z; And the method call: int a 1, b 2, c 3 int d enigma (a, b, c)i System.out.println ("Done!") What values do these variables have after this call to enigma returns (i.e. just before "Done" is print the screen)? (4 points) a m Consider the two code segments below (a and b), where x and y are int variables: a) if (x-y) x=x+1; Will these two code segments always produce the same assignments for x and y in the end, or are there certain values of x and/or y where they will behave differently? If you believe that they will behave the same way, provide a convincing argument in 1-2 sentences to explain why you believe that this is so. If you believe that they will behave differently, provide at least one example of values for x and y where they behave differently and describe the difference (5 points)
