For this homework, you must implement the following methods for CountingQueue: __len__ __iter__ __in__ __getitem__ Your goal is to have CountingQueue behave exactly like Queue to an outside user: the objects have to be different only due to their internal implementation. So for instance, __len__ must return the number of elements, including repetitions; not the number of (element, count) pairs in self. queue. Note that we are adding methods to a class that has already been defined, so our definition have the following somewhat unusual form:

The blank is type of decision-maker who over analyzes information

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.

The two main ways in which marketers address the competition with their strategies are by satisfying a need better than a competition and by
