unique substrings using suffix tree
- by user1708762
For a given string S of length n-
Optimal algorithm for finding all unique substrings of S can't be less than O(n^2). So, the best algorithm will give us the complexity of O(n^2). As per what I have read, this can be implemented by creating suffix tree for S.
The suffix tree for S can be created in O(n) time. Now, my question is-
How can we use the suffix tree for S to get all the unique substrings of S in O(n^2)?
