The continue command is used to resume execution until the next breakpoint is encountered in the Pdb debugger. It allows you to skip over code sections you're not interested in debugging.

The algorithm that follows the 'divide and conquer' strategy is Quick Sort. In Quick Sort, the array is divided into smaller subarrays, sorted separately, and then combined.

The process of visiting all the nodes of a tree and performing an operation is known as tree traversal. Tree traversal is essential for various tree-based algorithms and operations like printing the contents of a tree.

In Python, you can concatenate two tuples using the + operator. The + operator is used for concatenating sequences, including tuples. For example, tuple1 + tuple2 will combine the elements of both tuples.

To convert a list into a set in Python, you can use the set() constructor. It takes an iterable, such as a list, as an argument and creates a new set containing the unique elements from the list.

In Django, you create new URL patterns by adding them to the urls.py file of your app. This file maps URLs to view functions, allowing you to define the routing of your web application.

In Python, the pdb module is used for debugging. It allows you to set breakpoints, step through code, and inspect variable values during program execution.

In Python, to define a generator, you use the yield keyword within a function. A generator function produces an iterator, which can be used to generate a sequence of values lazily, conserving memory and improving performance.

To define a metaclass, you generally override the __new__ method. This method is responsible for creating the class itself and can be customized to modify class attributes and behavior during creation.

To enable database migrations in Flask, the Flask-Migrate extension is used. Flask-Migrate is an extension that integrates the Alembic database migration framework with Flask applications, allowing you to manage database schema changes easily.
