Describe the process of backtracking in regular expression matching and its implications.
- Mechanism where the algorithm explores various possibilities and reverts to previous choices if a solution cannot be found.
- Methodology that prioritizes forward progress and never revisits previous decisions.
- Strategy focused on always selecting the longest match in the input text.
- Technique that eliminates backtracking and guarantees a linear runtime.
Backtracking in regular expression matching involves exploring different possibilities and reverting to previous choices when needed. It allows the algorithm to search for all possible matches but may have implications on performance due to redundant exploration.
