Language: JAVA Script write a function 'keyValueDuplicates (obj) that takes an object as an argument and returns an array containing all keys that are also values in that object.  Examples:  obj1 = { orange: "juice", apple: "sauce", sauce: "pan" }; console.log(keyValueDuplicates (obj1)); // ["sauce"]  obj2 = { big: "foot", foot: "ball", ball: "boy", boy: "scout"}; console.log(keyValueDuplicates(obj2)); // ["foot", "ball", "boy"]  obj3 = { pizza: "pie", apple: "pie" pumpkin: "pie"); console.log(keyValueDuplicates (obj3)); // []  *******************************************************************/ function keyValueDuplicates (obj) {  |  // Your code here  } /*****DO NOT MODIFY ANYTHING UNDER THIS LINE*********

1. Implement a class IntArr using dynamic memory. a. data members: capacity: maximum number of elements in the array size: current number of elements in the array array: a pointer to a dynamic array of integers b. constructors: default constructor: capacity and size are 0, array pointer is nullptr user constructor: create a dynamic array of the specified size c. overloaded operators: subscript operator: return an element or exits if illegal index d. "the big three": copy constructor: construct an IntArr object using deep copy assignment overload operator: deep copy from one object to another destructor: destroys an object without creating a memory leak e. grow function: "grow" the array to twice its capacity f. push_back function: add a new integer to the end of the array g. pop_back function: remove the last element in the array h. getSize function: return the current size of the array (not capacity) i. Use the provided main function (next page) and output example Notes a. grow…

Create an Organization class. Organization has 10 Employees (Hint: You will need an array of pointers to Employee class) Organization can calculate the total amount to be paid to all employees Organization can print the details(name & salary) of all employees note: write code in main,header and function.cpp file
