Grid Total

Four whole numbers are read, one per line, into a 2 by 2 grid declared as a list of lists (the first two lines make the first row). Use nested for loops: the outer loop takes one row at a time and the inner loop adds that row's values into a row total, which is printed as Row total: <value> before the next row starts; afterwards print the sum of everything as Grid total: <value>. Input: four integers, no prompts.

Expected Output:

Row total: 7↵
Row total: 11↵
Grid total: 18↵

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