<p>Given two strings <code>s</code> and <code>t</code>, transform string <code>s</code> into string <code>t</code> using the following operation any number of times:</p>
|
|
|
|
<ul>
|
|
<li>Choose a <strong>non-empty</strong> substring in <code>s</code> and sort it in place so the characters are in <strong>ascending order</strong>.
|
|
|
|
<ul>
|
|
<li>For example, applying the operation on the underlined substring in <code>"1<u>4234</u>"</code> results in <code>"1<u>2344</u>"</code>.</li>
|
|
</ul>
|
|
</li>
|
|
</ul>
|
|
|
|
<p>Return <code>true</code> if <em>it is possible to transform <code>s</code> into <code>t</code></em>. Otherwise, return <code>false</code>.</p>
|
|
|
|
<p>A <strong>substring</strong> is a contiguous sequence of characters within a string.</p>

<p><strong class="example">Example 1:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> s = "84532", t = "34852"
|
|
<strong>Output:</strong> true
|
|
<strong>Explanation:</strong> You can transform s into t using the following sort operations:
|
|
"84<u>53</u>2" (from index 2 to 3) -> "84<u>35</u>2"
|
|
"<u>843</u>52" (from index 0 to 2) -> "<u>348</u>52"
|
|
</pre>
|
|
|
|
<p><strong class="example">Example 2:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> s = "34521", t = "23415"
|
|
<strong>Output:</strong> true
|
|
<strong>Explanation:</strong> You can transform s into t using the following sort operations:
|
|
"<u>3452</u>1" -> "<u>2345</u>1"
|
|
"234<u>51</u>" -> "234<u>15</u>"
|
|
</pre>
|
|
|
|
<p><strong class="example">Example 3:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> s = "12345", t = "12435"
|
|
<strong>Output:</strong> false
|
|
</pre>

|
<p> </p>
|
|
<p><strong>Constraints:</strong></p>
|
|
|
|
<ul>
|
|
<li><code>s.length == t.length</code></li>
|
|
<li><code>1 <= s.length <= 10<sup>5</sup></code></li>
|
|
<li><code>s</code> and <code>t</code> consist of only digits.</li>
|
|
</ul>
