A binary tree is a tree data structure in which each node has at most two child nodes, usually distinguished as "left" and "right". Nodes with children are parent nodes, and child nodes may contain references to their parents. Here is the source code of the Go program to implement Binary Tree

// Binary Tree in Golangpackage mainimport ("fmt""os""io")type BinaryNode struct {left? *BinaryNoderight *BinaryNodedata? int64}type BinaryTree struct {root *BinaryNode}func (t *BinaryTree) insert(data int64) *BinaryTree {if t.root == nil {t.root = &BinaryNode{data: data, left: nil, right: nil}} else {t.root.insert(data)}return t}func (n *BinaryNode) insert(data int64) {if n == nil {return} else if data <= n.data {if n.left == nil {n.left = &BinaryNode{data: data, left: nil, right: nil}} else {n.left.insert(data)}} else {if n.right == nil {n.right = &BinaryNode{data: data, left: nil, right: nil}} else {n.right.insert(data)}}??}func print(w io.Writer, node *BinaryNode, ns int, ch rune) {if node == nil {return}for i := 0; i < ns; i++ {fmt.Fprint(w, " ")}fmt.Fprintf(w, "%c:%v\n", ch, node.data)print(w, node.left, ns+2, 'L')print(w, node.right, ns+2, 'R')}func main() {tree := &BinaryTree{}tree.insert(100).insert(-20).insert(-50).insert(-15).insert(-60).insert(50).insert(60).insert(55).insert(85).insert(15).insert(5).insert(-10)print(os.Stdout, tree.root, 0, 'M')} C:\golang\time>go run binarytree.go M:100 L:-20 L:-50 L:-60 R:-15 R:50 L:15 L:5 L:-10 R:60 L:55 R:85C:\golang\time>
