Given an array of size n, a triplet (a[i], a[j], a[k]) is called a Magic Triplet if a[i] < a[j] < a[k] and i < j < k. Count the number of magic triplets in a given array.
Example 1:
Input: arr = [3, 2, 1]
Output: 0
Explanation: There is no magic triplet.
Your Task:
You don't need to read or print anything. Your task is to complete the function countTriplets() which takes the array nums[] as input parameter and returns the number of magic triplets in the array.
Expected Time Complexity: O(N2) Expected Space Complexity: O(N)

Avoid using static/global variables in your code as your code is tested
against multiple test cases and these tend to retain their previous values.
