Comparing Algorithm Efficiency

Definition

Comparing algorithms requires understanding trade-offs. Often, we can trade Space for Time (e.g., using a Hash Map uses O(N) space but drops lookup time from O(N) to O(1)).

Do you want it done fast (uses more memory) or do you want it to use less memory (takes longer)?
