In this video, we solve Leetcode 1930. Unique Length-3 Palindromic Subsequences using Java. Question Link - https://leetcode.com/problems/unique-length-3-palindromic-subsequences/description/?envType=daily-question&envId=2025-11-21 Solution: https://github.com/deepak-sharma-iOS/Leetcode-Daily-Challenge/blob/main/Leetcode-1930.java Summary: This solution checks each character from 'a' to 'z' and finds its first and last occurrence in the string. For each such pair, it counts how many distinct characters appear between them. Each distinct middle character forms a unique 3-length palindromic subsequence, and the total count is returned.
