In an alien language, surprisingly, they also use English lowercase letters, but possibly in a different
order of the alphabet is some permutation of lowercase letters.
Given a sequence of
words written in the alien language, and the
order of the alphabet, return
true if and only if the given
words are sorted lexicographically in this alien language.
Input: words = ["hello","leetcode"], order = "hlabcdefgijkmnopqrstuvwxyz" Output: true Explanation: As 'h' comes before 'l' in this language, then the sequence is sorted.
Input: words = ["word","world","row"], order = "worldabcefghijkmnpqstuvxyz" Output: false Explanation: As 'd' comes after 'l' in this language, then words > words, hence the sequence is unsorted.
Input: words = ["apple","app"], order = "abcdefghijklmnopqrstuvwxyz" Output: false Explanation: The first three characters "app" match, and the second string is shorter (in size.) According to lexicographical rules "apple" > "app", because 'l' > '∅', where '∅' is defined as the blank character which is less than any other character (More info).
1 <= words.length <= 100
1 <= words[i].length <= 20
order.length == 26
orderare English lowercase letters.
