Given two strings: s1 and s2 with the same size, check if some permutation of string s1 can break some permutation of string s2 or vice-versa. In other words s2 can break s1 or vice-versa.

\n\n

A string x can break string y (both of size n) if x[i] >= y[i] (in alphabetical order) for all i between 0 and n-1.

\n\n

 

\n

Example 1:

\n\n
\nInput: s1 = "abc", s2 = "xya"\nOutput: true\nExplanation: "ayx" is a permutation of s2="xya" which can break to string "abc" which is a permutation of s1="abc".\n
\n\n

Example 2:

\n\n
\nInput: s1 = "abe", s2 = "acd"\nOutput: false \nExplanation: All permutations for s1="abe" are: "abe", "aeb", "bae", "bea", "eab" and "eba" and all permutation for s2="acd" are: "acd", "adc", "cad", "cda", "dac" and "dca". However, there is not any permutation from s1 which can break some permutation from s2 and vice-versa.\n
\n\n

Example 3:

\n\n
\nInput: s1 = "leetcodee", s2 = "interview"\nOutput: true\n

Constraints:

\n\n\n", "translatedTitle": "检查一个字符串是否可以打破另一个字符串", "translatedContent": "

给你两个字符串 s1 和 s2 ,它们长度相等,请你检查是否存在一个 s1  的排列可以打破 s2 的一个排列,或者是否存在一个 s2 的排列可以打破 s1 的一个排列。

\n\n

字符串 x 可以打破字符串 y (两者长度都为 n )需满足对于所有 i(在 0 到 n - 1 之间)都有 x[i] >= y[i](字典序意义下的顺序)。

\n\n

 

\n\n

示例 1:

\n\n
输入:s1 = "abc", s2 = "xya"\n输出:true\n解释:"ayx" 是 s2="xya" 的一个排列,"abc" 是字符串 s1="abc" 的一个排列,且 "ayx" 可以打破 "abc" 。\n
\n\n

示例 2:

\n\n
输入:s1 = "abe", s2 = "acd"\n输出:false \n解释:s1="abe" 的所有排列包括:"abe","aeb","bae","bea","eab" 和 "eba" ,s2="acd" 的所有排列包括:"acd","adc","cad","cda","dac" 和 "dca"。然而没有任何 s1 的排列可以打破 s2 的排列。也没有 s2 的排列能打破 s1 的排列。\n
\n\n

示例 3:

\n\n
输入:s1 = "leetcodee", s2 = "interview"\n输出:true\n
