How does the performance of regular expression matching change with the complexity of the pattern and input text?

  • Performance degrades exponentially with the complexity of the pattern and input text.
  • Performance improves as both pattern and input text become more complex.
  • Performance is independent of the pattern complexity but depends on the input text complexity.
  • Performance remains constant regardless of the complexity of the pattern and input text.
The performance of regular expression matching typically degrades exponentially with the complexity of both the pattern and input text. More complex patterns and longer input texts can lead to significantly increased processing time.
