2901. Longest Unequal Adjacent Groups Subsequence II

Leetcode Solutions

Initialize a matrix hamming to store the Hamming distances between all pairs of words.
Precompute the Hamming distances and fill the hamming matrix.
Initialize a DP array dp to store the length of the longest subsequence ending at each word.
Initialize a prev array to store the previous index in the subsequence for each word.
Iterate over each word and update the dp and prev arrays based on the conditions.
Find the index of the last word in the longest subsequence by finding the maximum value in the dp array.
Reconstruct the longest subsequence by backtracking through the prev array.
Return the reconstructed subsequence.
