WebJun 3, 2024 · A binary tree is a recursive data structure where each node can have 2 children at most. A common type of binary tree is a binary search tree, in which every node has a value that is greater than or equal to the node values in the left sub-tree, and less than or equal to the node values in the right sub-tree. WebBinary tree traversals: PreOrder traversal – In PreOrder traversal,each node is processed before either of its sub-trees.In simpler words,Visit each node before its children.
