First, the template functionFunction templates provide an abstraction of a class of functions that represent a class of functions. When a function template is instantiated, it generates a concrete template function. For example, here is a function

Binary tree is a nonlinear structure, and traversal of binary tree is accomplished by recursive or non-recursive traversal by means of a stack assist. When a binary tree is used as a storage structure, it takes a node to get the left child and the
