Explain how the Manacher's algorithm can be adapted to solve the longest common substring problem efficiently.

  • Apply Manacher's algorithm only to the first string in the set.
  • Apply Manacher's algorithm separately to each string and compare the results.
  • Manacher's algorithm is not applicable to the longest common substring problem.
  • Utilize Manacher's algorithm on the concatenated strings with a special character between them.
Manacher's algorithm can be adapted for the longest common substring problem by concatenating the input strings with a special character between them and then applying the algorithm. This approach efficiently finds the longest common substring across multiple strings.
