You have:
\begin{itemize}
\item A matrix of natural numbers, with the property that all rows and all columns are sorted in ascending order (i.e. \textbf{A\[i, j\]} ≥ \textbf{A\[i-1, j\]} and \textbf{A\[i, j\]} ≥ \textbf{A\[i, j-1\],}

\textbf{i}, \textbf{j})
\item One or several pairs of numbers (\textbf{X}, \textbf{Y}) with the property that \textbf{Y} ≥ \textbf{X}.
\end{itemize}
For each (\textbf{X}, \textbf{Y}) pair, count how many numbers from the matrix are greater than or equal to \textbf{X} but smaller than or equal to \textbf{Y}.
\InputFile
The input file is a binary file containing \textbf{32}-bit integer numbers. The input file consists of:
\begin{itemize}
\item One integer \textbf{N} representing the number of rows (no more than \textbf{10000})
\item One integer \textbf{M} representing the number of columns (no more than \textbf{10000})
\item NxM integers, representing the values from the matrix, row by row
\item An unspecified number of integers, representing the (\textbf{X}, \textbf{Y}) pairs, one pair at a time. There will be at least one pair and at most \textbf{100} pairs in the file -- and there will not be an incomplete pair at the end of the file.
\end{itemize}
\OutputFile
For each pair you should write to standard output a value representing how many numbers in the matrix are greater than or equal to \textbf{X} but smaller than or equal to \textbf{Y}.
