<p>A sentence is a list of words that are separated by a single space with no leading or trailing spaces. For example, <code>"Hello World"</code>, <code>"HELLO"</code>, <code>"hello world hello world"</code> are all sentences. Words consist of <strong>only</strong> uppercase and lowercase English letters.</p>
|
|
|
|
<p>Two sentences <code>sentence1</code> and <code>sentence2</code> are <strong>similar</strong> if it is possible to insert an arbitrary sentence <strong>(possibly empty)</strong> inside one of these sentences such that the two sentences become equal. For example, <code>sentence1 = "Hello my name is Jane"</code> and <code>sentence2 = "Hello Jane"</code> can be made equal by inserting <code>"my name is"</code> between <code>"Hello"</code> and <code>"Jane"</code> in <code>sentence2</code>.</p>
|
|
|
|
<p>Given two sentences <code>sentence1</code> and <code>sentence2</code>, return <code>true</code> <em>if </em><code>sentence1</code> <em>and </em><code>sentence2</code> <em>are similar.</em> Otherwise, return <code>false</code>.</p>

<p><strong>Example 1:</strong></p>
|
|
|
|
<pre>

|
|
<pre>
|
