你需要找到一个长度最短的、与给定搜索模板匹配的回文串。回文串是指正读和反读都相同的字符串（空串也是回文串）。模板可以包含小写拉丁字母（对应字符串中相同的字母）、符号 '?'（对应任意一个小写拉丁字母）以及符号 '*'（对应零个或多个任意小写拉丁字母）。

输入格式

第一行包含一个字符串 $s$，即模板字符串。该字符串仅包含小写拉丁字母、符号 '?' 和 '*'。

$1 \le |s| \le 500$

输出格式

你需要输出一行，包含一个与给定模板匹配的长度最短的回文串。该回文串应仅包含小写拉丁字母。如果不存在这样的回文串，请输出 "-1"。如果存在多个满足条件的回文串，你可以输出其中任意一个。
