"content": "<p>You are given an array of equal-length strings <code>words</code>. Assume that the length of each string is <code>n</code>.</p>\n\n<p>Each string <code>words[i]</code> can be converted into a <strong>difference integer array</strong> <code>difference[i]</code> of length <code>n - 1</code> where <code>difference[i][j] = words[i][j+1] - words[i][j]</code> where <code>0 <= j <= n - 2</code>. Note that the difference between two letters is the difference between their <strong>positions</strong> in the alphabet i.e. the position of <code>'a'</code> is <code>0</code>, <code>'b'</code> is <code>1</code>, and <code>'z'</code> is <code>25</code>.</p>\n\n<ul>\n\t<li>For example, for the string <code>"acb"</code>, the difference integer array is <code>[2 - 0, 1 - 2] = [2, -1]</code>.</li>\n</ul>\n\n<p>All the strings in words have the same difference integer array, <strong>except one</strong>.

"translatedContent": "<p>给你一个字符串数组 <code>words</code> ，每一个字符串长度都相同，令所有字符串的长度都为 <code>n</code> 。</p>\n\n<p>每个字符串 <code>words[i]</code> 可以被转化为一个长度为 <code>n - 1</code> 的 <strong>差值整数数组</strong> <code>difference[i]</code> ，其中对于 <code>0 <= j <= n - 2</code> 有 <code>difference[i][j] = words[i][j+1] - words[i][j]</code> 。注意两个字母的差值定义为它们在字母表中 <strong>位置</strong> 之差，也就是说 <code>'a'</code> 的位置是 <code>0</code> ，<code>'b'</code> 的位置是 <code>1</code> ，<code>'z'</code> 的位置是 <code>25</code> 。</p>\n\n<ul>\n\t<li>比方说，字符串 <code>\"acb\"</code> 的差值整数数组是 <code>[2 - 0, 1 - 2] = [2, -1]</code> 。</li>\n</ul>\n\n<p><code>words</code> 中所有字符串 <strong>除了一个字符串以外</strong> ，其他字符串的差值整数数组都相同。你需要找到那个不同的字符串。</p>\n\n<p>请你返回<em> </em><code>words</code>中 <strong>差值整数数组</strong> 不同的字符串。</p>\n\n<p> </p>\n\n<p><strong>示例 1：</strong></p>\n\n<pre>\n<b>输入：</b>words = [\"adc\",\"wzy\",\"abc\"]\n<b>输出：</b>\"abc\"\n<b>解释：</b>\n- \"adc\" 的差值整数数组是 [3 - 0, 2 - 3] = [3, -1] 。\n- \"wzy\" 的差值整数数组是 [25 - 22, 24 - 25]= [3, -1] 。\n- \"abc\" 的差值整数数组是 [1 - 0, 2 - 1] = [1, 1] 。\n不同的数组是 [1, 1]，所以返回对应的字符串，\"abc\"。\n</pre>\n\n<p><strong>示例 2：</strong></p>\n\n<pre>\n<b>输入：</b>words = [\"aaa\",\"bob\",\"ccc\",\"ddd\"]\n<b>输出：</b>\"bob\"\n<b>解释：</b>除了 \"bob\" 的差值整数数组是 [13, -13] 以外，其他字符串的差值整数数组都是 [0, 0] 。\n</pre>\n\n<p> </p>\n\n<p><strong>提示：</strong></p>\n\n<ul>\n\t<li><code>3 <= words.length <= 100</code></li>\n\t<li><code>n == words[i].length</code></li>\n\t<li><code>2 <= n <= 20</code></li>\n\t<li><code>words[i]</code> 只含有小写英文字母。</li>\n</ul>\n",
