In Django, what is the name of the file used to define the URL patterns of an app?
- links.py
- patterns.py
- routes.py

In Django, the file used to define URL patterns for an app is usually named urls.py. This file maps URLs to views, helping Django route incoming requests to the appropriate view functions.
In Django, what is the role of a "view"?
- Defining the database schema
- Handling HTTP requests and returning HTTP responses

Securely managing user passwords in Flask involves hashing and salting them before storage. This ensures that even if the database is compromised, attackers can't easily recover passwords.
In algorithm analysis, ____ denotes the upper bound of the running time of an algorithm.
- Big-O
- O-notation
- Θ-notation
- Ω-notation
In algorithm analysis, Big-O notation (often represented as O-notation) denotes the upper bound of the running time of an algorithm. It provides an upper limit on how the algorithm's runtime scales with input size.
