Regular Expression Matching

Implement matching for patterns that include dot and star wildcards.

Hard

Implement matching for patterns that include dot and star wildcards.

Use the 2-d dynamic programming pattern to design an efficient solution and explain the tradeoffs in your approach.

Examples

Input: See starter test cases
Output: Expected result depends on the selected implementation
Explanation: These local prompts are original practice stubs and can be replaced by backend-provided examples later.

Constraints

  • Inputs follow the shape implied by the prompt title.
  • Prefer an approach that matches the named pattern track.
  • Optimize for clarity first, then improve time and space complexity.

Test Cases
