What are some practical exercises for learning data structures?

You can start with implementing basic data structures like arrays, linked lists, and stacks. Would you like specific examples?

Yes, can you give me an example of a linked list implementation?

Sure! A simple linked list can be implemented in Python like this:

class Node:
    def __init__(self, data):
        self.data = data
        self.next = None

class LinkedList:
    def __init__(self):
        self.head = None

    def append(self, data):
        new_node = Node(data)
        if not self.head:
            self.head = new_node
            return
        last = self.head
        while last.next:
            last = last.next
        last.next = new_node

Would you like to know how to traverse this linked list?

Yes, how do I traverse it?

You can traverse the linked list by starting from the head and moving to the next node until you reach the end. Here's a simple method:

def traverse(self):
    current = self.head
    while current:
        print(current.data)
        current = current.next
