Greedy Approach with Single Pass

  1. Initialize an empty list result to store the words of the longest subsequence.
  2. Add the first word from the words array to result.
  3. Initialize a variable last_group with the value of the first element in groups.
  4. Iterate over the groups array starting from the second element.
  5. For each element in groups, check if it is different from last_group.
  6. If it is different, add the corresponding word from words to result and update last_group with the current group value.
  7. Continue until the end of the groups array.
  8. Return the result list.
