How does the longest common substring problem differ from the longest common subsequence problem?
- In the longest common substring problem, the characters in the common sequence can appear in any order.
- In the longest common substring problem, the characters in the common sequence must appear consecutively.
- The longest common substring problem allows for overlapping substrings.
- The longest common substring problem deals with strings of equal length only.
The primary difference between the longest common substring problem and the longest common subsequence problem is that in the longest common substring problem, the characters in the common sequence must appear consecutively within the strings, whereas in the longest common subsequence problem, the characters do not have to be contiguous.
