Given a point $(x, y, z)$ in 3D space.

Find the squared distance from this point to the origin (i.e., to the point $(0, 0, 0)$ ).

Recall that the distance between two points $(x_{1}, y_{1}, z_{1})$ and $(x_{2}, y_{2}, z_{2})$ is defined by the formula

(x_{1} - x_{2})^{2} + (y_{1} - y_{2})^{2} + (z_{1} - z_{2})^{2}

Input

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

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

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

Output one integer.

Input #1

Answer #1

In the first test, we are interested in the squared distance from the point $(1, - 3, 5)$ to $(0, 0, 0)$ .

Substituting the coordinates into the formula, we get:

((1 - 0)^{2} + (- 3 - 0)^{2} + (5 - 0)^{2})^{2} =

= (1 + 9 + 25)^{2} = 35
