2. Explain when we can have the best case and when we can have the worst case. Give the complexity of your algorithm in each case. ● Best case: Question 1: 0 Worst case: Given an array, that can contain zeros, positive and negative elements. 1. Write an algorithm that calculates the number of positive elements (>0), the number of negative elements, and the number of zeros. Example: ● -5 Number of positive elements: 2 Number of negative elements: 3 Number of zeros: 3 Algorithm: wwwmmm -7 0 -6 8 0
