Given a matrix of R rows and C columns,
for each element print the sum of the adjacent elements.
Input
Format:
The first line contains R The second line
contains C Next R lines each contains C values separated by a space
Output
Format:
R lines each containing C values which
represent the sum of the adjacent elements.
Boundary
Conditions:
2 <= R,C <= 50 1 <= Matrix Elements <= 100
Example
Input/Output 1:
Input:
5 5
11 11 5 6 18
12 4 16 9 19
12 4 16 9 19
5
20 7 5 2
20 19 7 2 11
16 18 5 16 17
Output:
11 16 17 23 6
4 28 13 35 9
20 12 25 9 5
19 27 21 18 2
18 21 34 22 16
Solution:
n,m=int(input()),int(input())
a = [[int(x) for x in input().split()]for
_ in range(n)]
for x in a:
for i in range(len(x)):
if i == 0:
print(x[i+1],'',end='')
elif i == len(x)-1:
print(x[i-1],'',end='')
else:
print(x[i+1]+x[i-1],'',end='')
print()
