public class MaxPairWiseProduct3 extends Object

Maximum Pairwise Product (Brute-Force File Evaluation)

Evaluates the maximum pairwise product from a dataset of integers loaded dynamically from an external text file. This specific implementation utilizes a Naive Combinatorial Approach to evaluate all possible pairs.

Complexity

  • Time Complexity: O(N²) - The nested loop structure forces the algorithm to multiply every element against every other element. As the dataset scales, the total number of operations grows quadratically, demonstrating a severe performance bottleneck.
  • Space Complexity: O(N) - Requires linear memory allocation to store the entire dataset within a dynamic list structure during execution.

      public long compute()
      Computes the mathematical product iteratively by comparing every unique pair.

      Architectural Note: A strict 64-bit cast is applied during the multiplication step (long) to prevent intermediate 32-bit arithmetic overflow prior to assignment.

      Returns:
      The highest mathematical pairwise product found in the dataset.
