Video Summary :
Approach 1 (Brute Force):
Uses four nested loops to check every possible combination of indices (i, j, k, l) for matching products. The direct, but very inefficient, method.
Approach 2 (Slightly Improved Brute Force):
Similar to the brute force method but sorts the array first and adjusts the looping strategy to reduce some redundant checks. Sorting helps with early exits on conditions.
Approach 3 (Better Brute Force with HashSet):
After sorting, uses a hash set to track potential pairs. This reduces the complexity by eliminating one loop and leveraging the set for quick lookups of matching products.
Approach 4 (Mathematical Combination):
Efficiently counts pairs of products using a hashmap, then calculates the number of valid tuples based on frequency counts. Leverages combinatorial math to replace brute force counting.
