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

because the question just said the tree just 10 nodes，then following is my answer after read other answers：

func Walk(t *tree.Tree, ch chan int) {
    defer close(ch)

    var walker func(t *tree.Tree)
    walker = func(t *tree.Tree) {
        if t == nil {
            return
        }

        walker(t.Left)
        ch <- t.Value
        walker(t.Right)
    }
    walker(t)
}

func Same(t1, t2 *tree.Tree) bool {
    ch1, ch2 := make(chan int), make(chan int)
    go Walk(t1, ch1)
    go Walk(t2, ch2)

    for range make([]struct{}, 10) {
        if <-ch1 != <-ch2 {
            return false
        }
    }
    return true
}
