Explanation:

You can iterate through an array and use counters to keep track of each category in order to count the positive, negative, and zero elements.

Logic:

  1. Initialize Counters:
    • positive_count = 0
    • negative_count = 0
    • zero_count = 0
  2. Iterate Through the Array:
    • For each element:
      • If the element is greater than 0, increment positive_count
      • If the element is less than 0, increment negative_count
      • If the element is equal to 0, increment zero_count
  3. Output:
    • After processing all elements, return or print the values of the three counters.
