There is an array with n integers, but the values are hidden to us. Our goal is to partition the elements into groups based on their values – elements in the same group should have the same value, while elements in different groups have different values. The values are hidden to us so you cannot directly call for a value, like Arr[i]. However, we can probe the array by calling the function query(). The function takes a subset of elements as inputs and returns the number of unique integers in this subset. Design an algorithm to partition these n elements in O(nlog n) queries. (query() is called O(nlogn) times) 4.

Write a program that reads an array A of N elements containing only 0's and 1's. Your program should find the position of a 0 and replace it with a 1 to get the longest continuous sequence of 1's. Let this position of 0 be called P. Print P if such a 0 exists and print -1 if the original array A contains only 1's. Assume the array indexing starts from 0.
A set of data is given with the rebound height of tennis balls in centimeters from height 250cm (data.txt). Write three MatLab user-defined functions: usersort, GroupData and MeanStD. The function xo = usesort(x) should be able to sort an array in ascending order, the function [f, X] = GroupData(x) should create labels of the data and should return the labels X and the number of data for each label f and the function [A,s] = MeanStD(x) should return the mean value and the standard deviation as defined by the last equations in the slides 11 and 12. The labels X should start from the smallest round integer (use fix in MatLab) and should go until the largest round integer (use fix) with interval equal to 1. Each label should count the points that are smaller by half interval until larger by half interval. Calculate the density function of the Gauss distribution and define the following probabilities that a randomly chosen value of x will be: (i) no greater than 174cm, (ii) between 174cm…
İN C PROGRAMMİNG.Write a function that takes 20x20 array of real numbers as a parameter. The function should returnthe number of elements that are greater than the average of their neighbors (NOT-Including the diagonal neighbors)Example: In a 3x3 array : { {1, 3, 5},{7, 2, 4},{0, -2, 9} } element 5 is greater than the average of its neighbors (3,4) element 2 is not greater than the average of its neighbors (7,-2,3,4} element 4 is not greater than the average of its neighbors (5,2,9) Hint: You may consider Divide&Conquer and implement some other function to be called in the solution
Write a program that will take a pointer to the array as input and calculate if the number on which currently pointer has any two number pair in the array (after that number); that sums equal to that number. For example, if we have array; [5,3,4,1,2] then it must return [5,3] as both have sum pair.Note: No subscript operator” [ ]” will be used during this task on pointerarithmetic allowed e.g. *(ptr+1).
Implement a function GetMinimumCutSegments(int[] arr, int k) that takes in an array arr of positive integers and an integer k, and returns the minimum number of contiguous segments of the array that must be concatenated to form an array of size k. The function should return -1 if it is not possible to create an array of size k by concatenating contiguous segments of the input array. Example: Input: [1, 2, 3, 4], 6 Output: 2 Explanation: The minimum number of contiguous segments that must be concatenated to form an array of size 6 is 2. The two segments that can be concatenated are [1, 2] and [3, 4]. Input: [1, 2, 3, 4], 7 Output: -1 Explanation: It is not possible to create an array of size 7 by concatenating contiguous segments of the input array. Constraints: The input array arr will have at most length 100. The integer k will be at least 1 and at most 10^6. Can you write a C# function that solves this problem? public int GetMinimumCutSegments(int[] arr, int k) { // Your code…
An array is positive dominant if it contains strictly more unique positive values than unique negative values. Write a function that returns true if an array is positive dominant. Examples ispositiveDominant([1, 1, 1, 1, -3, -4]) // There is only 1 unique positive value (1). // There are 2 unique negative values (-3, -4). ispositiveDominant([5, 99, 832, -3, -4]) → true ispositiveDominant([5, 0]) → true ispositive Dominant([0, -4, -1]) → false
Write a function to find the maximum sum of a subarray within a given array of integers. The subarray should be contiguous, meaning the elements are adjacent to each other in the array. For example, given the array [-2, 1, -3, 4, -1, 2, 1, -5, 4], the maximum sum of a subarray is 6, which corresponds to the subarray [4, -1, 2, 1]. Write a function named `maxSubarraySum` that takes an array of integers as input and returns the maximum sum of a subarray. Note: If all the elements in the array are negative, the function should return O. Example: Input: [-2, 1, -3, 4, -1, 2, 1, -5, 4] Output: 6 Input: [-1, -2, -3, -4] Output: 0 Write the 'maxSubarraySum` function that solves this problem efficiently.
