What are circular references in data structures?
Circular references occur when two or more data structures reference each other, creating a loop.
Can you give me an example of a circular reference?
Sure! In a linked list, if the last node points back to the first node, that's a circular reference.
What problems can circular references cause?
They can lead to infinite loops in traversals and memory leaks if not handled properly.
How can I avoid circular references in my code?
You can use techniques like weak references or design your data structures to prevent loops.
