Trace: two variables

Line 1: a = 11a = 1
Line 2: b = 102b = 10
Line 3: a = a + b3a = a + b

Line 5: b = a - b5b = a - b
Line 6: print(b)6print(b)

Fill in one row each time a line changes a or b, or prints something. The table already has the right number of rows. In each row, write only what that line changes; you can leave the other cells empty or copy their values down. Write values the way Python shows them: 3 and 3.0 are different, and text goes in quotes. In the output column, write exactly what appears on screen, with no quotes around it.
