    593 - Valid Square\. Medium Given the coordinates of four points in 2D space `p1`, `p2`, `p3` and `p4`, return `true` _if the four points construct a square_. The coordinate of a point pi is represented as [xi, yi]. The input is **not** given in any order. A **valid square** has four equal sides with positive length and four equal angles (90-degree angles). **Example 1:** **Input:** p1 = [0,0], p2 = [1,1], p3 = [1,0], p4 = [0,1] **Output:** true **Example 2:** **Input:** p1 = [0,0], p2 = [1,1], p3 = [1,0], p4 = [0,12] **Output:** false **Example 3:** **Input:** p1 = [1,0], p2 = [-1,0], p3 = [0,1], p4 = [0,-1] **Output:** true **Constraints:** * `p1.length == p2.length == p3.length == p4.length == 2` * -104 <= xi, yi <= 104
