Part 2 The questions in thE part ofthe omgnmenr will be graded. First. you should download the attached java files to this assignment from MyConrses. Question 1: ArraySum [3|] points] la) Method to transform a number of an array In ArraySam calss, write a method called transform that receives an integer number and transforms it tn an integer array such that the array elements are digits oflnpnt integer number. For example: int |] transformU234) should retum the integer array [1, 2, 3, cl] 1b) Method to compute the sum of two arrays that represent a very big number. In ArraySum class. write a method called sum that receives two integer arrays olequa] size [each of these arrays is created by transform method) and returns an array of integer digits that corresponds to the sum. algorithm for sum funclinn: [r1 math, we first add digits at the rightmost index "i". lfresult of "digits addition" is greater than 9 then, we have a carry that needs to be added to digits at index "i—1" location, and so on, to complete addition digit by digit Example: transform(1234j -: a which is [1. 2, 3, 4] transfonn(1211) —:- b which is [1, 2, 1, 1] sum(a. b] -:v [EA-.45] transform(9295j -:- x which is [9, 2, 9. 5] sumta, x} —> [1,D,S,2,9]

Question 3: Rotate a 2D Array [30 points] In ItotateJaua, complete the method of rotateISD. The method receives a 20 array of integers and rotates the given In array in 1800 degree: {clockwise}. Assume matrix "a" represent a 2D array as follows: lllillllilllllillllillllill llillllillllillllilllliil 11 12 13 14 15 16 1? 13 19 20 liillliilllli'lliilllliil After running the rotateifllla] the matrix should be changed (in—place] such that it has 180 degrees rotation of elements. Therefore; after running rotatelmla} the matrix "a" will change to the following matrix: 20 19 13 1? 16 15 14 13 12 11 10 9 8 Ta" 6
