Задача 21773. Lazy Vasya and the release of Half-Life 3


A miracle happened! The long-awaited Half-Life 3, which millions of people around the world dreamed of, is finally out! Vasya was also looking forward to the continuation of the legendary series, and did not even eat in the school cafeteria for a whole month, so that he would have enough to buy this masterpiece! The only problem that stands in his way is a huge algebra homework assignment. In class, he went through a new topic - straight lines, and now he needs to do as many as N tasks on building a straight line through 2 points. But you really want to play, and the next day tell your friends what a cool graphic there is ... Therefore, he asked you, his friend, to help him.
 
Input
The first line contains the coordinates of the first point (X1, Y1), (\(-50 <= X_1, Y_1 <= 50\)).
The second line contains the coordinates of the second point (X2, Y2), (\(-50 <= X_2, Y_2 <= 50\)).
 
Output
On a single line print 3 integers in a row: the coefficients a, b, c of the equation of a straight line.
 
Note: if your task doesn't work, but you are sure that everything is correct, try multiplying all coefficients by -1. The task assumes that you have used formulas taken from the lecture/theory.
