Go Tour Exercise: Equivalent Binary Trees

Question

I am trying to solve equivalent binary trees exercise on go tour. Here is what I did;

package main

import \"tour/tree\"
import \"fmt\"

// Walk walks the tr         


        

Answer 1

That's how I did it using Inorder Traversal

package main

import (
    "fmt"
    "golang.org/x/tour/tree"
)

// Walk walks the tree t sending all values
// from the tree to the channel ch.
func Walk(t *tree.Tree, ch chan int) {
    if t != nil {
        Walk(t.Left, ch)
        ch <- t.Value
        Walk(t.Right, ch)
    }
}

// Same determines whether the trees
// t1 and t2 contain the same values.

func Same(t1, t2 *tree.Tree) bool {
    c1, c2 := make(chan int), make(chan int)
    go Walk(t1, c1)
    go Walk(t2, c2)
    if <-c1 == <-c2 {
        return true
    } else {
        return false
    }
}

func main() {
    t1 := tree.New(1)
    t2 := tree.New(8)
    fmt.Println("the two trees are same?", Same(t1, t2))
}
