593 - Valid Square.<p>Medium</p> <p>Given the coordinates of four points in 2D space <code>p1</code>, <code>p2</code>, <code>p3</code> and <code>p4</code>, return <code>true</code> <em>if the four points construct a square</em>.</p> <p>The coordinate of a point <code>p_i</code> is represented as <code>[x_i, y_i]</code>. The input is <strong>not</strong> given in any order.</p> <p>A <strong>valid square</strong> has four equal sides with positive length and four equal angles (90-degree angles).</p> <p><strong>Example 1:</strong></p> <p><strong>Input:</strong> p1 = [0,0], p2 = [1,1], p3 = [1,0], p4 = [0,1]</p> <p><strong>Output:</strong> true</p> <p><strong>Example 2:</strong></p> <p><strong>Input:</strong> p1 = [0,0], p2 = [1,1], p3 = [1,0], p4 = [0,12]</p> <p><strong>Output:</strong> false</p> <p><strong>Example 3:</strong></p> <p><strong>Input:</strong> p1 = [1,0], p2 = [-1,0], p3 = [0,1], p4 = [0,-1]</p> <p><strong>Output:</strong> true</p> <p><strong>Constraints:</strong></p> <ul> <li><code>p1.length == p2.length == p3.length == p4.length == 2</code></li> <li><code>-10⁴ <= x_i, y_i <= 10⁴</code></li> </ul>
