Download "ADDING 1 to n" program in "COURSE MATERIALS" . Find the runtime function as a function n. Remember f count each operative statement (of course comments don't count). Also write the order ("Big O"). Show work.

Write a program that uses a widgetviewer object to do the following: generate two random integers between 1 and 9 (inclusive). name one of them x, the other y. display them to the user using jlabel objects. create a jlabel object displaying the text "enter an operation number." create a jtextfield for the user's input. create a jbutton displaying the text "press here when you've entered your operation." use addandwait to add it to the widgetviewer object. when the user clicks the jbutton, evaluate operation in the following order to determine the one and only mathematical operation to perform on x and y. use a jlabel to display the result. if operation is between 1 and 10 inclusive, add x and y. if operation is evenly divisible by 4, subtract y from x. if operation is evenly divisible by 5, use integer division to divide y into x. if operation is an even number, use floating point division to divide y into x. if none of the other tests on operation apply, multiply x and y. note: operation can be negative or zero.

Need asap assignment directions: think of an organization (business, religious institution, volunteer organization, sports team) with which you have been involved. imagine outfitting it with an it infrastructure. prepare a plan for what you would do to support outfitting it. draw a map of a network connecting all the individuals, give them pcs and printers, and lay out the design as best you can. the purpose is to begin working with these concepts, not to build a perfect network.
