Finding Ranks

Ram is putting pins on graph on integer coordinates and giving ranks to the pins. All the pins are having $x \geq 0$ and $y \geq 0$ . Lets us denote that the rank given to $k^{th}$ pin is $R_k$ having coordinate $x_k$ and $y_k$. For any two coins i , j: if ($x_i + y_i$) Given U , V: write the rank of pin at (U,V) (given that U and V will both be an integer). Input: - First line will
