Description

Given two matrices $A$ and $B$ of size $n \times m$, output their sum $A+B$.

Input Format

First line contains two integers $n$ and $m$, representing the number of rows and columns of the matrices. $1 \le n \le 100$, $1 \le m \le 100$.
Next $n$ lines, each containing $m$ integers, represent the elements of matrix $A$.
Next $n$ lines, each containing $m$ integers, represent the elements of matrix $B$.
Adjacent integers are separated by a single space, and each element is between $1$ and $1000$.

Output Format

Output $n$ lines, each containing $m$ integers, representing the result of matrix addition. Adjacent integers are separated by a single space.
