- Implemented the Rabin–Karp string search algorithm in R.
- Finds all occurrences of a pattern in a given text using rolling hash.
- Efficient for multiple pattern searches in large texts.
- Handles case-insensitive input.
- Prints the starting positions of all matches.
- Time Complexity: O(n + m) average, O(n*m) worst case.
- Space Complexity: O(1)
