- Finds the most efficient way to multiply a sequence of matrices using dynamic programming.
- Efficient O(n³) DP implementation with optimal parenthesization generation.
- Handles edge cases including single matrices and finds all optimal solutions.
- Prints DP table, split table, and cost analysis with real-world examples.
- Time Complexity: O(n³) where n = number of matrices.
- Space Complexity: O(n²) for DP table.
