Solution
This problem can be solved using a brute force approach or a more efficient approach using a Binary Indexed Tree (BIT) or a Segment Tree. Here, I will explain the brute force approach.
Step 1: Initialize a variable total_count to 0. This will keep track of the total count of smaller elements on the right side of each element in the array.
Step 2: Loop through the array from left to right. For each element, initialize a variable count to 0. This will keep track of the count of smaller elements on the right side of the current element.
Step 3: For each element, loop through the rest of the array on its right. If any element on the right is smaller than the current element, increment count by 1.
Step 4: After the inner loop finishes for an element, add count to total_count.
Step 5: Repeat steps 2 to 4 for all elements in the array.
Step 6: After the outer loop finishes,
