<p>给定一个单词数组 <code>words</code> 和一个长度 <code>maxWidth</code> ,重新排版单词,使其成为每行恰好有 <code>maxWidth</code> 个字符,且左右两端对齐的文本。</p> <p>你应该使用 “<strong>贪心算法</strong>” 来放置给定的单词;也就是说,尽可能多地往每行中放置单词。必要时可用空格 <code>' '</code> 填充,使得每行恰好有 <em>maxWidth</em> 个字符。</p> <p>要求尽可能均匀分配单词间的空格数量。如果某一行单词间的空格不能均匀分配,则左侧放置的空格数要多于右侧的空格数。</p> <p>文本的最后一行应为左对齐,且单词之间不插入<strong>额外的</strong>空格。</p> <p><strong>注意:</strong></p> <ul> <li>单词是指由非空格字符组成的字符序列。</li> <li>每个单词的长度大于 0,小于等于 <em>maxWidth</em>。</li> <li>输入单词数组 <code>words</code> 至少包含一个单词。</li> </ul> <p> </p> <p><strong>示例 1:</strong></p> <pre> <strong>输入: </strong>words = ["This", "is", "an", "example", "of", "text", "justification."], maxWidth = 16 <strong>输出:</strong> [ "This is an", "example of text", "justification. " ] </pre> <p><strong>示例 2:</strong></p> <pre> <strong>输入:</strong>words = ["What","must","be","acknowledgment","shall","be"], maxWidth = 16 <strong>输出:</strong> [ "What must be", "acknowledgment ", "shall be " ] <strong>解释: </strong>注意最后一行的格式应为 "shall be " 而不是 "shall be", 因为最后一行应为左对齐,而不是左右两端对齐。 第二行同样为左对齐,这是因为这行只包含一个单词。 </pre> <p><strong>示例 3:</strong></p> <pre> <strong>输入:</strong>words = ["Science","is","what","we","understand","well","enough","to","explain","to","a","computer.","Art","is","everything","else","we","do"],maxWidth = 20 <strong>输出:</strong> [ "Science is what we", "understand well", "enough to explain to", "a computer. Art is", "everything else we", "do " ] </pre> <p> </p> <p><strong>提示:</strong></p> <ul> <li><code>1 <= words.length <= 300</code></li> <li><code>1 <= words[i].length <= 20</code></li> <li><code>words[i]</code> 由小写英文字母和符号组成</li> <li><code>1 <= maxWidth <= 100</code></li> <li><code>words[i].length <= maxWidth</code></li> </ul>
