Consider the following code segment: ArrayList scales = new ArrayList ();
scales. add("DO");
scales. add("RE");
scales. add("MI");
scales. add("FA");
scales. add("SO");
String swap = scales. get(2);
scales. remove(2);
String set = scales. remove(scales. size()-1);
scales. add(scales. get(0));
scales. set(0,set);
scales. add(scales. size()/2, swap);

Which of the following represents the value of scales after the code has been executed?

[SO, RE, FA, DO]

[SO, RE, MI, FA, DO]

[SO, RE, MI, DO]

[FA, RE, MI, DO]

[FA, SO, RE, MI, DO]

Perform the following tasks: a. create a class named testclass that holds a single private integer field and a public constructor. the only statement in the constructor is one that displays the message “constructing”. write a main()function that instantiates one object of the testclass. save the file as testclass.cpp in the chapter 08 folder. run the program and observe the results. b. write another main()function that instantiates an array of 10 testclass objects. save the file as test class array.c . run this program and observe the results.

Suppose you have 9 coins and one of them is heavier than others. other 8 coins weight equally. you are also given a balance. develop and algorithm to determine the heavy coin using only two measurements with the of the balance. clearly write your algorithm in the form of a pseudocode using the similar notation that we have used in the class to represent sorting algorithms
