//Given two sequences pushed and popped with distinct values, 
//return true if and only if this could have been the result of a sequence of push and pop operations on an initially empty stack.
 

//Example 1:

//Input: pushed = [1,2,3,4,5], popped = [4,5,3,2,1]
//Output: true
//Explanation: We might do the following sequence:

// Print Immutable Linked List in Reverse
// immutable linked list, print out all values of each node in reverse

// APIs:
// ImmutableListNode: An interface of immutable linked list, you are given the head of the list.
// You need to use the following functions to access the linked list (you can't access the ImmutableListNode directly):
// ImmutableListNode.printValue(): Print value of the current node.
// ImmutableListNode.getNext(): Return the next node.

# getNext() -> ImmutableListNode or None
