Print Matrix

Given $n\times n$ matrix — let's call it $[\mathrm{1..}n]\times [\mathrm{1..}n]$ array. For given values $r$ and $c$ print the $[\mathrm{1..}r]\times [\mathrm{1..}c]$ array ($r$ rows and $c$ columns of the given array).

Input

First line contains number $n(1\le n\le 100)$. Next lines contains the $n\times n$ matrix. The last line contains two integers $r$ and $c(1\le r,c\le n)$. All numbers in the matrix are no more than $100$ by absolute value.

Output

Print $r\times c$ matrix.
