<p>Given an array of strings <code>words</code> and a width <code>maxWidth</code>, format the text such that each line has exactly <code>maxWidth</code> characters and is fully (left and right) justified.</p>
<p>You should pack your words in a greedy approach; that is, pack as many words as you can in each line. Pad extra spaces <code>&#39; &#39;</code> when necessary so that each line has exactly <code>maxWidth</code> characters.</p>
<p>Extra spaces between words should be distributed as evenly as possible. If the number of spaces on a line does not divide evenly between words, the empty slots on the left will be assigned more spaces than the slots on the right.</p>
<p>For the last line of text, it should be left-justified and no extra space is inserted between words.</p>
<p><strong>Note:</strong></p>
<ul>
<li>A word is defined as a character sequence consisting of non-space characters only.</li>
<li>Each word&#39;s length is guaranteed to be greater than 0 and not exceed maxWidth.</li>
<li>The input array <code>words</code> contains at least one word.</li>
</ul>
<p>&nbsp;</p>
<p><strong>Example 1:</strong></p>
<pre>
<strong>Input:</strong> words = [&quot;This&quot;, &quot;is&quot;, &quot;an&quot;, &quot;example&quot;, &quot;of&quot;, &quot;text&quot;, &quot;justification.&quot;], maxWidth = 16
<strong>Output:</strong>
[
&nbsp; &nbsp;&quot;This &nbsp; &nbsp;is &nbsp; &nbsp;an&quot;,
&nbsp; &nbsp;&quot;example &nbsp;of text&quot;,
&nbsp; &nbsp;&quot;justification. &nbsp;&quot;
]</pre>
<p><strong>Example 2:</strong></p>
<pre>
<strong>Input:</strong> words = [&quot;What&quot;,&quot;must&quot;,&quot;be&quot;,&quot;acknowledgment&quot;,&quot;shall&quot;,&quot;be&quot;], maxWidth = 16
<strong>Output:</strong>
[
&nbsp; &quot;What &nbsp; must &nbsp; be&quot;,
&nbsp; &quot;acknowledgment &nbsp;&quot;,
&nbsp; &quot;shall be &nbsp; &nbsp; &nbsp; &nbsp;&quot;
]
<strong>Explanation:</strong> Note that the last line is &quot;shall be &quot; instead of &quot;shall be&quot;, because the last line must be left-justified instead of fully-justified.
Note that the second line is also left-justified becase it contains only one word.</pre>
<p><strong>Example 3:</strong></p>
<pre>
<strong>Input:</strong> words = [&quot;Science&quot;,&quot;is&quot;,&quot;what&quot;,&quot;we&quot;,&quot;understand&quot;,&quot;well&quot;,&quot;enough&quot;,&quot;to&quot;,&quot;explain&quot;,&quot;to&quot;,&quot;a&quot;,&quot;computer.&quot;,&quot;Art&quot;,&quot;is&quot;,&quot;everything&quot;,&quot;else&quot;,&quot;we&quot;,&quot;do&quot;], maxWidth = 20
<strong>Output:</strong>
[
&nbsp; &quot;Science &nbsp;is &nbsp;what we&quot;,
&quot;understand &nbsp; &nbsp; &nbsp;well&quot;,
&nbsp; &quot;enough to explain to&quot;,
&nbsp; &quot;a &nbsp;computer. &nbsp;Art is&quot;,
&nbsp; &quot;everything &nbsp;else &nbsp;we&quot;,
&nbsp; &quot;do &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&quot;
]</pre>
<p>&nbsp;</p>
<p><strong>Constraints:</strong></p>
<ul>
<li><code>1 &lt;= words.length &lt;= 300</code></li>
<li><code>1 &lt;= words[i].length &lt;= 20</code></li>
<li><code>words[i]</code> consists of only English letters and symbols.</li>
<li><code>1 &lt;= maxWidth &lt;= 100</code></li>
<li><code>words[i].length &lt;= maxWidth</code></li>
</ul>
