[Q3] Sequence Comparison

The main reason why it is acceptable a saving of space while increasing the execution time with the improvement for the basic sequence comparison algorithm is:

1. It is imperative to save space at any cost since the processing of normal sequences for real problems demands more RAM than any average computer can have nowadays.
2. The increment in execution time is merely theoretical, considering the processing capacity of current computers.
3. The increment in execution time is constant with this improvement.
4. Time complexity remains the same with this improvement.
5. None of the above
