Step 1
State two benefits of developing solutions using the structured approach.
Answer
-
Improved Testing and Error Discovery: Solutions developed using a structured approach, such as subroutines, allow for individual components to be tested in isolation. This makes it easier to discover and fix errors since each part of the solution can be verified independently.
-
Ease of Update and Maintenance: Using a structured approach enables developers to update subroutines without affecting the entire program. This modularity enhances maintainability and allows code to be modified with minimal risk of introducing new errors.
Step 2
Fill in the blank arrays to show the steps involved in applying the bubble sort.
Answer
- Initialize the Array: Start with an unsorted array of numbers.
- Compare Adjacent Elements: Iterate through the array, comparing each pair of adjacent elements.
- Swap if Necessary: If the first element is greater than the second, swap them.
- Repeat for Entire Array: Continue the comparison across the whole array, ensuring the largest unsorted element 'bubbles' to the end.
- Repeat Until Sorted: Repeat the above steps until no swaps are needed, indicating the array is sorted.
