使用地图进行实施

Question

我正在尝试使用go来实现Trie数据结构，但我不熟悉该语言，也不使用地图，并且想知道是否有一些技巧可以解释我的一些递归因此它没有＆＃39看起来很糟糕。如果我能得到一些关于如何使添加方法更好（更少的代码行）的帮助，也将不胜感激。

刚刚注意到树本身在添加单词时永远不会知道的问题，所以绝对可以解决这个问题！

// The overall tree
type TrieTree struct { 
    root TrieNode
    count int
}

// The node for each character inside the tree
type TrieNode struct {
    letter string // this is the value of the current node 
    isWord bool // if this letter + all of its parents make a word set = to true 
    children map[string]*TrieNode // maps children nodes
}

//method for adding a word into the tree
func (root *TrieNode, entry string) AddEntry() {
    //in case someone is trying to mess you up
    if (entry != nil || len(entry) != 0 || root != nil) {
        entry = strings.ToLower(entry)
        AddEntryHelper(root, entry, 0)
    }
}

func (node *TrieNode, entry string, count int) AddEntryHelper() {
    // the last one and no child yet
    if(node.children == nil && count == len(entry)-1) { 
        node.children=(map[string(entry[count])]=TrieNode{string(entry[count]), true, nil})
    // no children and not last one
    } else if(node.children == nil && count != len(entry)-1) { 
        node.children=(map[string(entry[count])]=TrieNode{string(entry[count]), false, nil})
        AddEntryHelper(node.children[string(entry[count])], entry, count++) 
    // last one and child exist
    } else if (node.children != nil && count == len(entry)-1) {
        node.children[string(entry[count])].isWord = true
    // children node exists and just need to recurse down
    } else {
        AddEntryHelper(node.children[string(entry[count])], entry, count++)
    }
}
