- This is a great technique to get students out of their comfort zones and working on creative problem solving.
- If students get stuck, provide them with some of the following suggestions for modifying their code:
- Change for-loops to while-loops.
- Convert arrays to ArrayLists.
- Change Strings to character arrays.
- Tell students that certain data structures or data types cannot be used.
- This added helps them figure out how to change their code without changing their output.
- For instance, disallow use of the multiplication (*) operator.
- This forces students to think about how to implement a multiply() function and get creative.
- Students can use a for-loop or recursive addition. Give them a chance to figure it out on their own and be creative.
