Episode notes
Memoization: Trading Space for Time
- Memoization is a powerful technique that trades space for time.
- It uses more memory to decrease computation time, sometimes significantly improving function speed.
Memoization as a Cache
- Memoization acts as an automatic cache, storing function results to avoid recomputation.
- The initial call is slow, but subsequent calls with the same arguments become faster lookups.
When to Use Memoization
- Use memoization when calling the same function with the same arguments repeatedly.
- It's ineffective if arguments always differ; it shines when reusing arguments frequently.
