Given an array of integers and a positive integer k, find the maximum sum of any contiguous subarray of size k. For example, given the array [1, 2, 3, 4, 5] and k = 2, the maximum sum is 7, which is the sum of the subarray [4, 5]   Please solve in C# language

Write a Java program that computes and prints out the sum of 1 + 2 + .. + 100Note: Your output will show:“The sum of 1 + 2 + .. + 100 is xxx” where xxx is computed by your Java program.

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

Given an array, find the next greater element for each element in the array, ifavailable. If not available, print the element itself. The next greater element y for anelement x in the array is the first element that is greater than x and occurs on its rightside. The next greater element of the right most element in an array is the elementitself.Example: Given A = [ 6 8 4 3 9] the next greater element listB = [8 9 9 9 9].
