Test instructions: There are two linked lists, which represent two non-negative numbers in reverse order. Example (2, 4, 3) represents 342, which is two digits and is output in reverse order in the same way. As 342+465 = 807, you need to show the

Problem:Given a singly linked list where elements is sorted in ascending order, convert it to a height balanced BST.Idea: Go through the linked list first, put the value into a vector, and then the vector of ordered data to build a balanced binary
