Description

For the gray value of each pixel of an image in n rows and m columns, you must use the following method to blur it:

1. The gray value of the outermost pixel remains unchanged;

2. The new gray value of each pixel in the middle is the average of the original gray value of the pixel and its upper and lower left and right adjacent four pixels (rounded to the nearest integer ).

Input

The first line contains two integers n and m, indicating that the image contains the number of rows and columns of pixels. 1 <= n <= 100, 1 <= m <=.
In the next n rows, each row has m integers, indicating the gray scale of each pixel of the image. Two Adjacent integers are separated by a single space. Each element ranges from 0 ~ In the range of 255.

Output

N rows, m integers in each row, are the blurred images. Two Adjacent integers are separated by a single space.
