When implementing a stack using a linked list vs array, which statement is WRONG?

For the push and pop functions, using array is much faster because otherwise a linked list always requires traversing to the node at the end

A linked list is a better option in terms of flexible stack capacity without requiring memory copy

It's possible to use the front of an array as the 'top' of the stack (correct)

Stack implemented using a linked list has a slightly higher storage overhead comparing to array due to the additional 'next' variables in each node

Which of the following is WRONG for binary tree?

There's always one root node in a tree

Each node can only have one parent node

It can be traversed (visiting all nodes) in more than one ways.

Each node always has two child nodes, except the leaf node which has none. (correct)

Which of the following is TRUE about implementing a stack using an array?

It's not possible to implement a stack using an array

The 'top' of the stack is always at the end of the array (correct)

Push and pop operations require traversing the entire array
