You are given an array arr[] of size n. Find the total count of sub-arrays having their sum equal to 0. Example 1: Input: n = 6 arr[] = {0,0,5,5,0,0} Output: 6 LJ r1
Design an algorithm that takes an array containing n distinct natural numbers. A number k ≤ n and calculates the sum of the k largest numbers in the array. For example, if the array is {3, 7, 5, 12, 6} and k = 3, then the algorithm should return 25 (12+7+6). You may freely use standard data structure/s and algorithms from the course in your solution
Use Java programming language Given a 2-D array, print all flag numbers in the array in any order. A flag number is an element of the array such that it is the minimum element in its row and maximum in its column. Example 1: Input: matrix = [[3,7,8],[9,11,13],[15,16,17]] Output: [15] Explanation: 15 is the only flag number since it is the minimum in its row and the maximum in its column.
