面试题 17.22 单词转换
给定字典中的两个词，长度相等。写一个方法，把一个词转换成另一个词， 但是一次只能改变一个字符。每一步得到的新词都必须能在字典中找到。
编写一个程序，返回一个可能的转换序列。如有多个可能的转换序列，你可以返回任何一个。
示例 1:
输入: beginWord = "hit", endWord = "cog", wordList = ["hot","dot","dog","lot","log","cog"] 输出: ["hit","hot","dot","lot","log","cog"]
示例 2:
输入: beginWord = "hit" endWord = "cog" wordList = ["hot","dot","dog","lot","log"] 输出: [] 解释: endWord "cog" 不在字典中，所以不存在符合要求的转换序列。
func findLadders(beginWord string, endWord string, wordList []string) []string {
}
