problem_description: Statement
  
  There is a square in the xy-plane. The coordinates of its four vertices are
  (x_1,y_1),(x_2,y_2),(x_3,y_3) and (x_4,y_4) in counter-clockwise order.
  (Assume that the positive x-axis points right, and the positive y-axis points
  up.)
  
  Takahashi remembers (x_1,y_1) and (x_2,y_2), but he has forgot (x_3,y_3) and
  (x_4,y_4).
  
  Given x_1,x_2,y_1,y_2, restore x_3,y_3,x_4,y_4. It can be shown that
  x_3,y_3,x_4 and y_4 uniquely exist and have integer values.
