467 - Unique Substrings in Wraparound String.

Medium

We define the string s to be the infinite wraparound string of "abcdefghijklmnopqrstuvwxyz", so s will look like this:

  • "...zabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcd....".

Given a string p, return the number of unique non-empty substrings of p are present in s.

Example 1:

Input: p = “a”

Output: 1 Explanation: Only the substring “a” of p is in s.

Example 2:

Input: p = “cac”

Output: 2

Explanation: There are two substrings (“a”, “c”) of p in s.

Example 3:

Input: p = “zab”

Output: 6

Explanation: There are six substrings (“z”, “a”, “b”, “za”, “ab”, and “zab”) of p in s.

Constraints:

  • 1 <= p.length <= 105
  • p consists of lowercase English letters.
