    467 - Unique Substrings in Wraparound String.

    Medium

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

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

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

    Example 1:

    Input: s = "a"

    Output: 1

    Explanation: Only the substring "a" of s is in base.

    Example 2:

    Input: s = "cac"

    Output: 2

    Explanation: There are two substrings ("a", "c") of s in base.

    Example 3:

    Input: s = "zab"

    Output: 6

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

    Constraints:

    • <code>1 <= s.length <= 10<sup>5</sup></code>

    • s consists of lowercase English letters.
