Consider the following MARIE Code: 100 If, Load X /Load the first value 101 Subt Y /Subtract the value of Y, store result in AC 102 Skipcond 400 /If AC=0 (X=Y), skip the next instruction 103 Jump Else /Jump to Else part if AC is not equal to 0 104 Then, Load X /Reload X so it can be doubled 105 Add X /Double X Charles Sturt University Subject Outline ITC544 202030 SM I Version 2 - Published 25 March 2020 Page 19 of 39 106 Store X /Store the new value 107 Jump Endif /Skip over the false, or else, part to the end of if 108 Else, Load Y /Start the else part by loading Y 109 Subt X /Subtract X from Y 10A Store Y /Store Y-X in Y 10B Endif, Halt /Terminate program (it doesn't do much!) 10C X, Dec 12 /Assume these values for X and Y 10D Y, Dec 20 Find the values stored in the following registers after the execution of "Skipcond 400" instruction: [5 marks] (i) PC (ii) IR (iii) MAR (iv) MBR (v) AC

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.

Write a method that takes in an array of point2d objects, and then analyzes the dataset to find points that are close together. be sure to review the point2d api. in your method, if the distance between any pair of points is less than 10, display the distance and the (x, y)s of each point. for example, "the distance between (3,5) and (8,9) is 6.40312." the complete api for the point2d adt may be viewed at ~pf/sedgewick-wayne/algs4/documenta tion/point2d. html (links to an external site.)links to an external site.. try to write your program directly from the api - do not review the adt's source code.
