The Odd Square

You will be given a grid $G$ of size $N$ x $M$. Each cell in this grid has a certain value $V[i][j]$. You will be asked $Q$ queries. Each query will consist of 3 integers $X$, $Y$ & $L$. Consider the square with side length $L$ (odd) and center ($X$,$Y$). ( $Xth$ row & $Yth$ Column ) You are supposed to find the **summation** of:- $V[Pi][Pj]$ * $MD(Pi,Pj)$ Where, ($Pi$,$Pj$) is any p
