Sum Of Each Row

The grid matrix has three rows of three integers; its centre cell is read from input() as one integer with no prompt. Loop over the rows with a for loop and print the total of each row with sum(), so three numbers appear, one per line, in row order. Input: one integer.

Expected Output:

12
18
15

= newline. The output ends with a newline — print one after the last line.
