Qwen Chat — Live Demo
Write a Python function to reverse a linked list
U
Q

Here's an efficient iterative solution:

def reverse_linked_list(head):
    prev = None
    current = head
    while current:
        next_node = current.next
        current.next = prev
        prev = current
        current = next_node
    return prev

Time complexity: O(n), Space: O(1). The algorithm reverses pointers in-place without using extra memory.
