Work every question in your notebook.

1. A student traced this code and made the table below. Which row is wrong first?

   k ← 3
   j ← k * 2
   k ← j
   j ← j + k

   1. Line 2 row
   2. Line 3 row
   3. Line 4 row
   4. Line 1 row

2. Build the header row, then trace all six lines.

   h ← 1
   g ← h + 9
   h ← g * 2
   f ← h - g
   g ← f + h
   show g

3. No line repeats. How many rows does this trace table need, not counting the header?

   d ← 4
   show d
   e ← d + 1
   show e
   d ← e * d
   show d
   e ← 0

   1. 6
   2. 7
   3. 5
   4. 4

4. Seven lines, two shows. Build the whole table, then submit it to check.

   a ← 3
   b ← a * 4
   c ← b - a
   show c
   a ← c + b
   b ← a - c
   show b
