Time Limit: 0.5 seconds Memory Limit: 256 megabytes ---------- A skilled thief intends to steal from a marble shop. To execute a flawless theft, first of all, he must find out the locations of the surveillance cameras in the shop. Through extensive research using his X-ray equipped satellite, he has obtained valuable information. Since he researched from above using the satellite, he sees the shop as a Cartesian coordinate plane where the southern and western walls of the shop are the x and y axes of the coordinates. He knows that there are four cameras in the shop, and the coordinates of these four cameras are the coordinates of the four vertices of a rectangle on this coordinate plane, whose sides are parallel to the coordinate axes. The thief has been able, through extensive research, to determine the coordinates of three out of the four cameras. But figuring out the location of the fourth camera was very difficult for him! By taking these three coordinates as input, tell him the coordinates of the fourth camera. # Input The input consists of three lines. In each line, two numbers $x$ and $y$ (separated by a space) are given, which are the coordinates of one of the cameras. It is guaranteed that these three points are the coordinates for three vertices of a rectangle whose area is greater than zero. $$ 0 \le x,y \le 1\ 000\ 000\ 000 $$ # Output In the single output line, print two numbers separated by a space, which respectively represent the $x$ and $y$ of the fourth camera. # Example ## Sample Input 1 ``` 1 2 3 4 1 4 ``` ## Sample Output 1 ``` 3 2 ```
