"content": "<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>\n\n<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>' '</code> when necessary so that each line has exactly <code>maxWidth</code> characters.</p>\n\n<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>\n\n<p>For the last line of text, it should be left-justified and no extra space is inserted between words.</p>\n\n<p><strong>Note:</strong></p>\n\n<ul>\n\t<li>A word is defined as a character sequence consisting of non-space characters only.</li>\n\t<li>Each word's length is guaranteed to be greater than 0 and not exceed maxWidth.</li>\n\t<li>The input array <code>words</code> contains at least one word.</li>\n</ul>\n\n<p> </p>\n<p><strong>Example 1:</strong></p>\n\n<pre>\n<strong>Input:</strong> words = ["This", "is", "an", "example", "of", "text", "justification."], maxWidth = 16\n<strong>Output:</strong>\n[\n "This is an",\n "example of text",\n "justification.
