Substrings of Size Three with Distinct Characters solution leetcode

Substrings of Size Three with Distinct Characters solution leetcode

A string is good if there are no repeated characters.

Given a string s​​​​​, return the number of good substrings of length three in s​​​​​​.

Note that if there are multiple occurrences of the same substring, every occurrence should be counted.

substring is a contiguous sequence of characters in a string.
