Write a method called manipulate-2-Dim that receives a two-dim array of integer numbers called a matrix. The method should return the sum of elements in the even rows of the array.
A method to make an almost sorted array into fully sorted.@param arr: an array of integers, with all the numbers are sortedexcepted the last one@param size: the number of elements in an array*/public static void insertLast(int[] arr, int size){// your work}To make it concrete, let's use the example shown in Figure 1. In this example, the arraycontains [1, 3, 4, 5, 6, 7, 2], and the size of the array is 7. As we can see, The inputarray are sorted excepted the last one. The goal here is to place last element into a correctposition so all numbers will be sorted. This is exactly what the method insertLast is toperform.1Figure 1: Sampel output for insertion sort part 1.As we recall from the lecture, the idea is keep shifting all larger number (compared with thelast number) to the right until we nd the number is smaller than the last number. In ourexample,1. Compare 7 with 2. Since 7 > 2, we copy 7 to its right.2. Compare 6 with 2. Since 6 > 2, we copy 6 to its right.3. Compare 5 with…

Implement getArrayElmsInRange Method Details: getArrayElemsInRange public static int[] getArrayElemsInRange(int[] array, int lower, int upper) Returns an array with values in the range defined by lower (inclusive) and upper (inclusive). Feel free to use the getCountInRange method during the implementation of this method (See below). Parameters: array - integer array lower - lower limit upper - upper limit Returns: array with values in the range or empty array Throws: java.lang.IllegalArgumentException - if array is null or lower is greater than upper. Any error message is fine (e.g., "Invalid parameters(s)") getCountInRange Method: class Main { // this function will return the number elements in the given range public static int getCountInRange(int[] array, int lower, int upper) { int count = 0; // to count the numbers // this loop will count the numbers in the range for (int i…
Describe what the following static methods of the java.util.Arrays class do: asList, binarySearch, fill, and sort? Where there are multiple versions of a method, use one that operates on an integer array as the example.

Write a method swapArrayEnds() that swaps the first and last elements of its array parameter. Ex: sortArray = {10, 20, 30, 40} becomes {40, 20, 30, 10}. The array's size may differ from 4. new code can only be added between existing code. as seen in image.

Below is how the arrays are represented ARRAY1[] = [1, 5, 6, 6, 9, 9, 9, 11, 11, 21] Here length of ARRAY1 is m. ARRAY2[] = [6, 6, 9, 11, 21, 21, 21] Here length of ARRAY2 is n. Array to be returned would be: ARRAY[] = [6, 9, 11, 21] ATTN : Further, please be reminded that you cannot use library functions to either sort and or perform the de-duplication operation. solve the problem in two ways In a separate implementation, code up a solution in such a way that your solution solves the problem with O(nlog(m)) time complexity 2 or O(mlog(n)) time complexity. Here log means to the base of 2. I’m sure you already know that the hint is to use Binary Search. In the form of sentences, as a comment in your code (at the bottom of your Solution2), you are required to suggest how can Solution2 be improved by leveraging the fact that both the arrays are already sorted. Suggest a solution so that your suggested solution can run linearly with O(m + n) time complexity. Your suggestion should be no…
