"content": "<p>In an alien language, surprisingly, they also use English lowercase letters, but possibly in a different <code>order</code>. The <code>order</code> of the alphabet is some permutation of lowercase letters.</p>\n\n<p>Given a sequence of <code>words</code> written in the alien language, and the <code>order</code> of the alphabet, return <code>true</code> if and only if the given <code>words</code> are sorted lexicographically in this alien language.</p>\n\n<p> </p>\n<p><strong class=\"example\">Example 1:</strong></p>\n\n<pre>\n<strong>Input:</strong> words = ["hello","leetcode"], order = "hlabcdefgijkmnopqrstuvwxyz"\n<strong>Output:</strong> true\n<strong>Explanation: </strong>As 'h' comes before 'l' in this language, then the sequence is sorted.\n</pre>\n\n<p><strong class=\"example\">Example 2:</strong></p>\n\n<pre>\n<strong>Input:</strong> words = ["word","world","row"], order = "worldabcefghijkmnpqstuvxyz"\n<strong>Output:</strong> false\n<strong>Explanation: </strong>As 'd' comes after 'l' in this language, then words[0] > words[1], hence the sequence is unsorted.\n</pre>\n\n<p><strong class=\"example\">Example 3:</strong></p>\n\n<pre>\n<strong>Input:</strong> words = ["apple","app"], order = "abcdefghijklmnopqrstuvwxyz"\n<strong>Output:</strong> false\n<strong>Explanation: </strong>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 (<a href=\"https://en.wikipedia.org/wiki/Lexicographical_order\" target=\"_blank\">More info</a>).\n</pre>\n\n<p> </p>\n<p><strong>Constraints:</strong></p>\n\n<ul>\n\t<li><code>1 <= words.length <= 100</code></li>\n\t<li><code>1 <= words[i].length <= 20</code></li>\n\t<li><code>order.length == 26</code></li>\n\t<li>All characters in <code>words[i]</code> and <code>order</code> are English lowercase letters.</li>\n</ul>\n",
