题目标签:HashMap 题目给了我们一个 order 和 words array,让我们依照order 来判断 words array 是否排序. 利用hashmap 把order 存入 map, 写一个helper method 来判断每临近的两个 word 是否排序正确. 遍历words array,依次比较临近的两个words. 具体看code. Java Solution: Runtime: 5 ms, faster than 64.55% Memory Usage: 38.2 MB,…

某种外星语也使用英文小写字母,但可能顺序 order 不同.字母表的顺序(order)是一些小写字母的排列. 给定一组用外星语书写的单词 words,以及其字母表的顺序 order,只有当给定的单词在这种外星语中按字典序排列时,返回 true:否则,返回 false. 示例 1: 输入:words = ["hello","leetcode"], order = "hlabcdefgijkmnopqrstuvwxyz" 输出:true 解释:在该语…
