Problem:
Score : 200 points

Problem 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.

Constraints

|x_1|,|y_1|,|x_2|,|y_2| \leq 100

(x_1,y_1) ≠ (x_2,y_2)

All values in input are integers.

Input

Input is given from Standard Input in the following format:

x_1 y_1 x_2 y_2

Output

Print x_3,y_3,x_4 and y_4 as integers, in this order.

Sample Input 1

0 0 0 1

Sample Output 1

-1 1 -1 0

(0,0),(0,1),(-1,1),(-1,0) is the four vertices of a square in counter-clockwise order.
Note that (x_3,y_3)=(1,1),(x_4,y_4)=(1,0) is not accepted, as the vertices are in clockwise order.

Sample Input 2

2 3 6 6

Sample Output 2

3 10 -1 7

Sample Input 3

31 -41 -59 26

Sample Output 3

-126 -64 -36 -131

Solution in PyPy3 (2.4.0) (judge verdict: Wrong Answer)

x1, y1, x2, y2 = map(int, input().split())

#x_diff = 2 3 6 6
#diff = abs(x1-x2) if x1!=x2 else abs(y1-y2)

def up(x_pre, y_pre, x_diff, y_diff):
  return x_pre-x_diff, y_pre+y_diff

  return x_pre-x_diff, y_pre-y_diff
def down(x_pre, y_pre, x_diff, y_diff):
  return x_pre+x_diff, y_pre-y_diff
def right(x_pre, y_pre, x_diff, y_diff):
  return x_pre+x_diff, y_pre+y_diff

x_diff_ = x2 - x1
y_diff_ = y2 - y1
print(x_diff_, y_diff_)
rotate = []
if y_diff_ >= 0:
  if x_diff_ >= 0:
    print(1)
    rotate = [up, left]
  else:
    print(2)
    rotate = [left, down]
else:
  if x_diff_ >= 0:
    print(3)
    rotate = [right, up]
  else:
    print(4)
    rotate = [down, right]
  
x3, y3 = rotate[0](x2, y2, abs(y2-y1), abs(x2-x1))
print(abs(y2-y1), abs(x2-x1))
x4, y4 = rotate[1](x3, y3, abs(y3-y2), abs(x3-x2))
print(abs(y3-y2), abs(x3-x2))
