// The following mem file shows examples of the various opcode
// from part 0, but is not a real program (i.e. together these
// statements don't really do much).  The individual statements are

// line 0 and 1   - r0 <- 0
// line 2 and 3   - r1 <- 1
// line 4 and 5   - r2 <- 2
// line 6 and 7   - r0 <- r1 + r2
// line 8 and 9   - branch if r1 is 0; PC <- PC + 6
// line 10 and 11 - r0 <- r1
// line 12 and 13 - r1 <- 4
// line 14 and 15 - r2 <- 3
// line 16 and 17 - r0 <- r1 - r2
// line 18 and 19 - mem[r1] <- r2
// line 20 and 21 - r0 <- mem[r1]
