Write a program to create a double dimensional array of size n x m. Input the numbers in first (n-1) x (m-1) cells. Find and place the sum of each row and each column in corresponding cells of last column and last row respectively. Finally, display the array elements along with the sum of rows and columns.

Sample Input

10	15	16	18
15	14	12	11
11	12	16	17
12	10	14	16

Sample Output

10	15	16	18	59
15	14	12	11	52
11	12	16	17	56
12	10	14	16	52
48	51	58	62
