Implement a mergeUniqueValues(arr1, arr2) method. When passed two arrays of strings, it will return an array containing the strings that appear in either or both arrays in sorted order. And the returned array should have no duplicates. For example, if you have two string arrays: arr1: {“Bear”, “Elephant”,”Fox”}arr2: {“Panda”, “Elephant”,”Eagle”} Calling mergeUniqueValues(arr1, arr2) should return a merged and sorted array like: Bear, Eagle, Elephant, Fox, Panda
public static void reverseAscendingSubarrays(int[] items) Rearrange the elements of the given array of integers in place (that is, do not create and return a new array) so that the elements of every maximal strictly ascending subarray are reversed. For example, given the array {5, 7, 10, 4, 2, 7, 8, 1, 3}, after executing this method, the elements of the array would be {10, 7, 5, 4, 8, 7, 2, 3, 1}. Given another argument array {5, 4, 3, 2, 1}, the contents of that array would stay as {5, 4, 3, 2, 1} seeing that its each element is a maximal ascending subarray of length one. public static String pancakeScramble(String text) This nifty little problem is taken from the excellent Wolfram Challenges problem site where you can also see examples of what the result should be for various arguments. Given a text string, construct a new string by reversing its first two characters, then reversing the first three characters of that, and so on, until the last round where you reverse your entire…
implement a parametrized version of mergesort that will allow us to choose how many parts the input array will be divided into.This method will take an integer array and integer K as inputs and produce one integer array as output. It will sort the input array by dividing it into K parts, recursively sorting those parts, and using the mergeAll method to merge the K sorted arrays into one sorted array. Implement the mergesortK method public static int[] mergesortK(int[] arr, int k) { return new int[] {-1}; } *must be done in this format and in java please
Write a program in java that randomly fills in 0s and 1s into an n-by-n matrix, prints the matrix, and finds the rows and columns with the most 1s. (Hint: Use two ArrayLists to store the row and column indices with the most 1s.)

write a java program which creates A magic square is an n x n matrix which, if filled with numbers, the sum of the elements ineach row, each column, and the two diagonal is the same value. Write a program that asksthe user to for the size of an n x n matrix (square), stores the values in a two dimensionalarray and prints whether the values entered form a magic square.The program must use methods, loops and two dimensional arrays for thisassignment. The main method should show the flow of the program as discussed in class.Sample Run 1:Enter the size of the square3Enter the numbers in each row separated by a space1 1 11 1 11 1 1|1 1 1 ||1 1 1 ||1 1 1 |Magic SquareSample Run 2:Enter the size of the square4Enter the numbers in each row separated by a space1 1 1 11 2 1 11 1 1 11 1 1 1|1 1 1 1 ||1 2 1 1 ||1 1 1 1 ||1 1 1 1 |Not a Magic Square
in java lanuage please You have been given two sorted arrays (in increasing order), find a path through the intersectionsthat produces maximum sum and return the maximum sum.That is, you can switch from one array to another array only at common elements.If no intersection element is present, we need to take sum of all elements from the array with greatersum.Input Format:Line 1: Size of first arrayLine 2: Elements of first arrayLine 3: Size of second arrayLine 4: Elements of second arrayOutput Format:The maximum sumSample Input:61 5 10 15 20 2552 4 5 9 15Sample Output:81Explanation:We will start from second array and take sum till 5 which will be equal to 11. Then we'll switch tofirst array because both arrays are intersecting at 5 so then we will start from element 10 and take till15 and the sum will become 36. Now again both arrays are intersecting at 15 but there are noelements left in second array after 15, so we'll continue with first array. Hence sum will be 81. in java

FOR JAVA Write a method that takes a one dimensional integer array, an integer (as index) and another integer (as number). Your program must insert the number into the given index, shift the rest of the elements to the right, and return the new array. For instance, if we want to insert the number 0 into position 3 of {1, 2, 3, 4, 5}, your method must return {1, 2, 3, 0, 4, 5}.
