Given the following custom class myClass, which of the following statements are TRUE? Select all that apply. class myClass: _init_(self, code, name): self.code - code self.name= name self.roster = [] def def enrol(self, 1st: list[str]) -> None: ** Add each element of <1st> to the roster once. for item in 1st: if item not in self.roster: self.roster.append(1st) O The attribute roster cannot be defined, since it's not a parameter of the initializer. O The method enrol is correct. O The method enrol is incorrect because it doesn't properly add elements to the roster. O The method enrol is incorrect because it doesn't properly ignore duplicate string elements. O The method enrol is incorrect because it doesn't return anything. O The initializer is incorrect as it creates more attributes than are passed. O The command print(c.roster) prints the list roster, where c is an instance of myClass.

Program #11. Show the ArrayStackADT interface 2. Create the ArrayStackDataStrucClass<T> with the following methods: default constructor, overloaded constructor, copy constructor, initializeStack, isEmptyStack, isFullStack, push, peek, void pop 3. Create the PrimeFactorizationDemoClass: instantiate an ArrayStackDataStrucClass<Integer> object with 50 elements. Use a try-catch block in the main( ) using pushes/pops. 4. Exception classes: StackException, StackUnderflowException, StackOverflowException 5. Show the 4 outputs for the following: 3,960 1,234 222,222 13,780
in kotlin, Use this Employee class data class Employee(val name: String, val wage: Double, val hours: Double) and this list of Employees: val l: List = listOf(Employee("Bob", 34.33, 42.0), Employee ("Cathy", 27.33, 15.25), Employee("Carlos", 46.99, 38.75), Employee("Tomas", 49.66,28.45), Employee("Xavier", 34.56, 11.5)) Write a function called raise which takes a list of Employees and a Double and returns a list of Employees like the original but with each having received a raise, with the Double representing the percentage raise. For example, if an employee's wage was $20 per hour and the Double is .15 (that is, 15%), her new wage will be $23 per hour. Don't change the Employees; create and return a list of new Employee objects with the new wages. Use Kotlin's map() function.
Tests: In the test_sun.py module, create tests for the planet objects. You can (and should) do this before you have written any Planet code at all. Implementation: In the sun.py module (see template), implement a Sun class as described in Section 10.4. Your Sun class should include the following methods: __init__, get_mass, get_radius, get_temperature, and __str__. Your __str__ method should include the following information for each planet: Name, distance from sun, radius, and mass. section 10.4
In Kotlin, use this Employee class Use this Employee class data class Employee(val name: String, val wage: Double, val hours: Double) and this list of Employees: val l: List = listOf(Employee("Bob", 34.33, 42.0), Employee ("Cathy", 27.33, 15.25), Employee("Carlos", 46.99, 38.75), Employee("Tomas", 49.66,28.45), Employee("Xavier", 34.56, 11.5)) Write a function called formatPaycheck that takes a Pair and returns a String. formatPaycheck should use the two parts of the Pair to put together and return a String like this, with the paycheck amount shown to two digits past the decimal point: Pay to the order of Cathy $359.47 Use raise() to raise all the Employees' pay by 15%. Then use map with the payroll and formatPaycheck functions to get a list of the paychecks in the format shown above. Print the result. The output should look like this: [Pay to the order of Bob $1077.79, Pay to the order of Cathy $359.47, Pay to the order of Carlos $1361.09, Pay to the order of Tomas $1056.09,…
