Coordinates

Given a point $(x,y,z)$ in 3D space. Find the square of the distance from this point to the origin (i.e., to the point $(0,0,0)$).

Input

The first line contains one integer $x$ ($-100\le x\le 100$).

The second line contains one integer $y$ ($-100\le y\le 100$).

The third line contains one integer $z$ ($-100\le z\le 100$).

Output

Output one integer.
