Can you give me examples of data structure implementations?

Can you give me examples of data structure implementations?

Sure! Common data structures include arrays, linked lists, stacks, queues, trees, and graphs. Which one are you interested in?

Tell me more about linked lists.

A linked list is a linear data structure where elements are stored in nodes, each pointing to the next. It's dynamic and allows efficient insertions and deletions.

What about trees? How are they implemented?

Trees are hierarchical structures with nodes connected by edges. A common implementation is a binary tree, where each node has at most two children.

Can you show me a code example for a stack?

Certainly! Here's a simple stack implementation in Python:

class Stack:
    def __init__(self):
        self.items = []

    def push(self, item):
        self.items.append(item)

    def pop(self):
        return self.items.pop() if not self.is_empty() else None

    def is_empty(self):
        return len(self.items) == 0
