To construct a rectangle, you are given the coordinates of two opposite vertices. The sides of the rectangle are parallel to the coordinate axes. Write a program to find the coordinates of the other two vertices of the rectangle.
The first line contains four integers x_1, y_1, x_2, y_2 (-1000 \leq x_1, y_1, x_2, y_2 \leq 1000, x_1 \neq x_2, y_1 \neq y_2) — the coordinates of the given opposite vertices.
Output four integers x_3, y_3, x_4, y_4 — the coordinates of the other two vertices. Output the left vertex first, then the right vertex.
