题目标签:String 题目给了我们 对应每一个 字母的 morse 密码,让我们从words 中 找出 有几个不同的 morse code 组合. 然后只要遍历 words,把每一个word 转换成 morse code,把 唯一的 存入 HashSet 就可以了,最后返回 set 的 size. Java Solution: Runtime beats  99.77% 完成日期:07/02/2018 关键词:HashSet 关键点:把唯一morse code 存入 set class Sol…

国际摩尔斯密码定义一种标准编码方式,将每个字母对应于一个由一系列点和短线组成的字符串, 比如: "a" 对应 ".-", "b" 对应 "-...", "c" 对应 "-.-.", 等等. 为了方便,所有26个英文字母对应摩尔斯密码表如下: [".-","-...","-.-.","-..",".&…
