Algorithms

You are given two strings <code>s1</code> and <code>s2</code>, both of length <code>4</code>, consisting of lowercase English letters.

You can apply the following operation on any of the two strings any number of times:

<ul>
	<li>Choose any two indices <code>i</code> and <code>j</code> such that <code>j - i = 2</code>, then swap the two characters at those indices in the string.</li>
</ul>

Return <code>true</code> if you can make the strings <code>s1</code> and <code>s2</code> equal, and <code>false</code> otherwise.

&nbsp;
Example 1:

<pre>
Input: s1 = &quot;abcd&quot;, s2 = &quot;cdab&quot;
Output: true
Explanation: We can do the following operations on s1:
- Choose the indices i = 0, j = 2. The resulting string is s1 = &quot;cbad&quot;.
- Choose the indices i = 1, j = 3. The resulting string is s1 = &quot;cdab&quot; = s2.
</pre>

Example 2:

<pre>
Input: s1 = &quot;abcd&quot;, s2 = &quot;dacb&quot;
Output: false
Explanation: It is not possible to make the two strings equal.
</pre>

&nbsp;
Constraints:

<ul>
	<li><code>s1.length == s2.length == 4</code></li>
	<li><code>s1</code> and <code>s2</code> consist only of lowercase English letters.</li>
</ul>

Check if Strings Can be Made Equal With Operations I

String

给你两个字符串&nbsp;<code>s1</code> 和&nbsp;<code>s2</code>&nbsp;，两个字符串的长度都为&nbsp;<code>4</code>&nbsp;，且只包含 小写 英文字母。

你可以对两个字符串中的 任意一个&nbsp;执行以下操作 任意&nbsp;次：

<ul>
	<li>选择两个下标&nbsp;<code>i</code> 和&nbsp;<code>j</code>&nbsp;且满足&nbsp;<code>j - i = 2</code>&nbsp;，然后 交换 这个字符串中两个下标对应的字符。</li>
</ul>

如果你可以让字符串&nbsp;<code>s1</code> 和&nbsp;<code>s2</code>&nbsp;相等，那么返回 <code>true</code>&nbsp;，否则返回 <code>false</code>&nbsp;。

&nbsp;

示例 1：

<pre>
输入：s1 = "abcd", s2 = "cdab"
输出：true
解释： 我们可以对 s1 执行以下操作：
- 选择下标 i = 0 ，j = 2 ，得到字符串 s1 = "cbad" 。
- 选择下标 i = 1 ，j = 3 ，得到字符串 s1 = "cdab" = s2 。
</pre>

示例 2：

<pre>
输入：s1 = "abcd", s2 = "dacb"
输出：false
解释：无法让两个字符串相等。
</pre>

&nbsp;

提示：

<ul>
	<li><code>s1.length == s2.length == 4</code></li>
	<li><code>s1</code> 和&nbsp;<code>s2</code>&nbsp;只包含小写英文字母。</li>
</ul>
