If there are multiple such strings, return the lexicographically smallest one.

\n\n

Return a string denoting the answer to the problem.

Example 1:

\n\n
\nInput: a = "abc", b = "bca", c = "aaa"\nOutput: "aaabca"\nExplanation:  We show that "aaabca" contains all the given strings: a = ans[2...4], b = ans[3..5], c = ans[0..2]. It can be shown that the length of the resulting string would be at least 6 and "aaabca" is the lexicographically smallest one.
\n\n

Example 2:

\n\n
\nInput: a = "ab", b = "ba", c = "aba"\nOutput: "aba"\nExplanation: We show that the string "aba" contains all the given strings: a = ans[0..1], b = ans[1..2], c = ans[0..2]. Since the length of c is 3, the length of the resulting string would be at least 3. It can be shown that "aba" is the lexicographically smallest one.\n

Constraints:

\n\n\n", "translatedTitle": "包含三个字符串的最短字符串", "translatedContent": "给你三个字符串 a ,b 和 c , 你的任务是找到长度 最短 的字符串,且这三个字符串都是它的 子字符串 。\n

如果有多个这样的字符串,请你返回 字典序最小 的一个。

\n\n

请你返回满足题目要求的字符串。

\n\n

注意:

\n\n\n\n

 

\n\n

示例 1:

\n\n
输入:a = \"abc\", b = \"bca\", c = \"aaa\"\n输出:\"aaabca\"\n解释:字符串 \"aaabca\" 包含所有三个字符串:a = ans[2...4] ,b = ans[3..5] ,c = ans[0..2] 。结果字符串的长度至少为 6 ,且\"aaabca\" 是字典序最小的一个。
\n\n

示例 2:

\n\n
输入:a = \"ab\", b = \"ba\", c = \"aba\"\n输出:\"aba\"\n解释:字符串 \"aba\" 包含所有三个字符串:a = ans[0..1] ,b = ans[1..2] ,c = ans[0..2] 。由于 c 的长度为 3 ,结果字符串的长度至少为 3 。\"aba\" 是字典序最小的一个。\n
