Words[i j] and words[i j+1] are equal in length, and the. The problem asks you to find the longest subsequence from a given array of strings (`words`) such that consecutive strings in the subsequence have different corresponding group values in a separate. For adjacent indices in the subsequence, their corresponding groups are unequal, i.e., groups[i j] != groups[i j+1], for each j where 0 < j + 1 < k.

Another subsequence that can be selected is [a,b,d] because groups [0] != groups [1] and groups [1] != groups [3].
