963 - Minimum Area Rectangle II.<p>Medium</p> <p>You are given an array of points in the <strong>X-Y</strong> plane <code>points</code> where <code>points[i] = [x_i, y_i]</code>.</p> <p>Return <em>the minimum area of any rectangle formed from these points, with sides <strong>not necessarily parallel</strong> to the X and Y axes</em>. If there is not any such rectangle, return <code>0</code>.</p> <p>Answers within <code>10^-5</code> of the actual answer will be accepted.</p> <p><strong>Example 1:</strong></p> <p><img src="https://assets.leetcode.com/uploads/2018/12/21/1a.png" alt="" /></p> <p><strong>Input:</strong> points = [[1,2],[2,1],[1,0],[0,1]]</p> <p><strong>Output:</strong> 2.00000</p> <p><strong>Explanation:</strong> The minimum area rectangle occurs at [1,2],[2,1],[1,0],[0,1], with an area of 2.</p> <p><strong>Example 2:</strong></p> <p><img src="https://assets.leetcode.com/uploads/2018/12/22/2.png" alt="" /></p> <p><strong>Input:</strong> points = [[0,1],[2,1],[1,1],[1,0],[2,0]]</p> <p><strong>Output:</strong> 1.00000</p> <p><strong>Explanation:</strong> The minimum area rectangle occurs at [1,0],[1,1],[2,1],[2,0], with an area of 1.</p> <p><strong>Example 3:</strong></p> <p><img src="https://assets.leetcode.com/uploads/2018/12/22/3.png" alt="" /></p> <p><strong>Input:</strong> points = [[0,3],[1,2],[3,1],[1,3],[2,1]]</p> <p><strong>Output:</strong> 0</p> <p><strong>Explanation:</strong> There is no possible rectangle to form from these points.</p> <p><strong>Constraints:</strong></p> <ul> <li><code>1 <= points.length <= 50</code></li> <li><code>points[i].length == 2</code></li> <li><code>0 <= x_i, y_i <= 4 * 10⁴</code></li> <li>All the given points are <strong>unique</strong>.</li> </ul>
