PUZZLE 1 Click on Example #1. Notice that the conditional statement if-do determines which numbers are decorated. Change values and click Run Code to see the effect. For example, change Repeat number or Gork colour. What do you think number mod 3 = 0 means? Edit the code to get this pattern. |
PUZZLE 2 Click on Example #2. Notice that the conditional statement if-do-else. Edit the code to get this pattern: PUZZLE 3 Click on Example #3. What does the conditional code if ___ and ___ do? Edit the code to get this pattern.
