Lesson 8. October 22 - 28. Recursive functions. Two dimentional arrays.

Print Matrix

Given n * n matrix - let's call it [1..n] * [1..n] array. For given values r and c print the [1..r] * [1..c] array (r rows and c columns of the given array).

Input

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

Output

Print r * c matrix.
