+Tip: You can solve in sections with the parentheses above, as multiplication/division can be done in any order together without changing the result. It helps a little bit with cutting down the manual solving time, if you ask me.

+Just a little bit of math and tracking of a changing array.

+r[1] = r[3] * 2 = 38;
+r[4] = r[1] / 2 = 19;
+r[2] = r[4 % 3 = 1] / 3 = 38 / 3 = 12;
