An original string, consisting of lowercase English letters, can be encoded by the following steps:
\n\nFor example, one way to encode an original string "abcdefghijklmnop" might be:
["ab", "cdefghijklmn", "o", "p"].["ab", "12", "1", "p"]."ab121p".Given two encoded strings s1 and s2, consisting of lowercase English letters and digits 1-9 (inclusive), return true if there exists an original string that could be encoded as both s1 and s2. Otherwise, return false.
Note: The test cases are generated such that the number of consecutive digits in s1 and s2 does not exceed 3.
\n
Example 1:
\n\n\nInput: s1 = "internationalization", s2 = "i18n"\nOutput: true\nExplanation: It is possible that "internationalization" was the original string.\n- "internationalization" \n -> Split: ["internationalization"]\n -> Do not replace any element\n -> Concatenate: "internationalization", which is s1.\n- "internationalization"\n -> Split: ["i", "nternationalizatio", "n"]\n -> Replace: ["i", "18", "n"]\n -> Concatenate: "i18n", which is s2\n\n\n
Example 2:
\n\n\nInput: s1 = "l123e", s2 = "44"\nOutput: true\nExplanation: It is possible that "leetcode" was the original string.\n- "leetcode" \n -> Split: ["l", "e", "et", "cod", "e"]\n -> Replace: ["l", "1", "2", "3", "e"]\n -> Concatenate: "l123e", which is s1.\n- "leetcode" \n -> Split: ["leet", "code"]\n -> Replace: ["4", "4"]\n -> Concatenate: "44", which is s2.\n\n\n
Example 3:
\n\n\nInput: s1 = "a5b", s2 = "c5b"\nOutput: false\nExplanation: It is impossible.\n- The original string encoded as s1 must start with the letter 'a'.\n- The original string encoded as s2 must start with the letter 'c'.\n\n\n
\n
Constraints:
\n\n1 <= s1.length, s2.length <= 40s1 and s2 consist of digits 1-9 (inclusive), and lowercase English letters only.s1 and s2 does not exceed 3.原字符串由小写字母组成，可以按下述步骤编码：
\n\n例如，编码 \"abcdefghijklmnop\" 的一种方法可以描述为：
[\"ab\", \"cdefghijklmn\", \"o\", \"p\"] 。[\"ab\", \"12\", \"1\", \"p\"] 。\"ab121p\" 。给你两个编码后的字符串 s1 和 s2 ，由小写英文字母和数字 1-9 组成。如果存在能够同时编码得到 s1 和 s2 原字符串，返回 true ；否则，返回 false。
注意：生成的测试用例满足 s1 和 s2 中连续数字数不超过 3 。
\n\n
示例 1：
\n\n输入：s1 = \"internationalization\", s2 = \"i18n\"\n输出：true\n解释：\"internationalization\" 可以作为原字符串\n- \"internationalization\" \n -> 分割： [\"internationalization\"]\n -> 不替换任何元素\n -> 连接： \"internationalization\"，得到 s1\n- \"internationalization\"\n -> 分割： [\"i\", \"nternationalizatio\", \"n\"]\n -> 替换： [\"i\", \"18\", \"n\"]\n -> 连接： \"i18n\"，得到 s2\n\n\n
示例 2：
\n\n输入：s1 = \"l123e\", s2 = \"44\"\n输出：true\n解释：\"leetcode\" 可以作为原字符串\n- \"leetcode\" \n -> 分割： [\"l\", \"e\", \"et\", \"cod\", \"e\"]\n -> 替换： [\"l\", \"1\", \"2\", \"3\", \"e\"]\n -> 连接： \"l123e\"，得到 s1\n- \"leetcode\" \n -> 分割： [\"leet\", \"code\"]\n -> 替换： [\"4\", \"4\"]\n -> 连接： \"44\"，得到 s2\n\n\n
示例 3：
\n\n输入：s1 = \"a5b\", s2 = \"c5b\"\n输出：false\n解释：不存在这样的原字符串\n- 编码为 s1 的字符串必须以字母 'a' 开头\n- 编码为 s2 的字符串必须以字母 'c' 开头\n\n\n
示例 4：
\n\n输入：s1 = \"112s\", s2 = \"g841\"\n输出：true\n解释：\"gaaaaaaaaaaaas\" 可以作为原字符串\n- \"gaaaaaaaaaaaas\"\n -> 分割： [\"g\", \"aaaaaaaaaaaa\", \"s\"]\n -> 替换： [\"1\", \"12\", \"s\"]\n -> 连接： \"112s\"，得到 s1\n- \"gaaaaaaaaaaaas\"\n -> 分割： [\"g\", \"aaaaaaaa\", \"aaaa\", \"s\"]\n -> 替换： [\"g\", \"8\", \"4\", \"1\"]\n -> 连接 \"g841\"，得到 s2\n\n\n
示例 5：
\n\n输入：s1 = \"ab\", s2 = \"a2\"\n输出：false\n解释：不存在这样的原字符串\n- 编码为 s1 的字符串由两个字母组成\n- 编码为 s2 的字符串由三个字母组成\n\n\n
