  "task_description": "You are given two strings `s1` and `s2`, both of length `n`, consisting of **lowercase** English letters. You can apply the following operation on **any** of the two strings **any** number of times: Choose any two indices `i` and `j` such that `i < j` and the difference `j - i` is **even**, then **swap** the two characters at those indices in the string. Return `true`_ if you can make the strings _`s1`_ and _`s2`_ equal, and _`false`_ otherwise_. **Example 1:** ``` **Input:** s1 = \"abcdba\", s2 = \"cabdab\" **Output:** true **Explanation:** We can apply the following operations on s1: - Choose the indices i = 0, j = 2. The resulting string is s1 = \"cbadba\". - Choose the indices i = 2, j = 4. The resulting string is s1 = \"cbbdaa\". - Choose the indices i = 1, j = 5. The resulting string is s1 = \"cabdab\" = s2. ``` **Example 2:** ``` **Input:** s1 = \"abe\", s2 = \"bea\" **Output:** false **Explanation:** It is not possible to make the two strings equal. ``` **Constraints:** `n == s1.length == s2.length` `1 <= n <= 105` `s1` and `s2` consist only of lowercase English letters.",
