How to reverse a linked list in python
WebPushing onto the stack - O (1), constant time. Printing the stack - O (N), where N is the number of pushed nodes onto the stack. Hence, the time complexity to print the reverse of a linked list will be O (N) + O (N) + O (1) = o (2N+1) ~ O (N), where N is the total number of nodes in the list.

So if the list is like 2 -> 4 -> 6 -> 8, then the new reversed list will be 8 -> 6 -> 4 -> 2. To solve this, we will follow this approach − Define one procedure to perform list reversal in recursive way as solve (head, back)
WebHere, you ask Python to give you the complete list ( [::-1]) but going over all the items from back to front by setting step to -1. This is pretty neat, but reversed () is more efficient in terms of execution time and memory usage. It’s also more readable and explicit. So these are points to consider in your code.
