You are given a string, s, consisting of lowercase English letters. Your task is to find the length of the longest self-contained substring of s.
A substring t of s is called self-contained if:
t is not equal to the entire string s.
Every character in t does not appear anywhere else in s (outside of t).
In other words, all characters in t are completely unique to that substring within the string s.
Return the length of the longest self-contained substring. If no such substring exists, return -1.
