Q1

Consider the Array

`int[] arr = {1, 2, 3, 4, 5};`

What are the values in `arr` after the following code is executed?

`for (int i = 0; i < arr.length - 2; i++)`

`{`

`int temp = arr<u>i</u>;`

`arr<u>i</u> = arr<u>i+1</u>;`

`arr<u>i+1</u> = temp;`

`}`

Consider the method

public String mystery(String s)

{

String s1 = s.substring(0,1);

String s2 = s.substring(1,2);

String s3 = s.substring(2, s.length() - 2);

String s4 = s.substring(s.length() - 2, s.length() - 1);

String s5 = s.substring(s.length() - 1);

`if (s.length() <= 5)`
`return s5 + s4 + s3 + s2 + s1;`
`else`
`return s1 + s2 + mystery(s3) + s4 + s5;`
`}`

What is the output of

`System.out.println(mystery("ABNORMALITIES"));`
