2. Iteratively method using stack. Use a while loop, the condition of the loop is that either the current node is not null or the stack is not empty. If current node is not null, push it into the stack. If the node is null, this means we've gone to the leftmost of the remaining...

Given an array of numbers, verify whether it is the correct preorder traversal sequence of a binary search tree. You may assume each number in the sequence is unique. Follow up: Could you do it using only constant space complexity?
Schreiben Sie bei einem gegebenen Binärbaum eine iterative und rekursive Lösung, um den Baum mit Inorder-Traversal in C++, Java und Python zu durchlaufen. Im Gegensatz zu verknüpften Listen, eindimensionalen Arrays und anderen linearen Datenstrukturen, die in linearer Reihenfolge durchlaufe...
