In mathematics and computer science, a set is a collection in which order does not matter and there are no duplicates. in this problem, we are going to to define a class which wil allow us to create an object to represent a set of integers. you will write a program set.java to define the class set. each instance of the class set will be an object representing a set of integers.

Analyze the following code. int x = 1; while (0 < x) & & (x < 100) system.out.println(x++); a. the loop runs forever. b. the code does not compile because the loop body is not in the braces. c. the code does not compile because (0 < x) & & (x < 100) is not enclosed in a pair of parentheses. d. the numbers 1 to 99 are displayed. e. the numbers 2 to 100 are displayed.

Dean wants a quick way to look up staff members by their staff id. in cell q3, nest the existing vlookup function in an iferror function. if the vlookup function returns an error result, the text “invalid staff id” should be displayed by the formula. (hint: you can test that this formula is working by changing the value in cell q2 to 0, but remember to set the value of cell q2 back to 1036 when the testing is complete.)
