📚 Topic Summary
Unplugged array sorting with playing cards is a hands-on activity that demonstrates how computers sort data without using a computer. By using a deck of playing cards, learners can visually understand and physically perform sorting algorithms like selection sort, insertion sort, or bubble sort. This activity helps to illustrate fundamental computer science concepts such as comparison, swapping, and iterative processes in a tangible and engaging way.
This method involves representing data elements as playing cards and then following a specific set of rules (the sorting algorithm) to arrange them in ascending or descending order. It provides an excellent foundation for understanding more complex sorting algorithms used in computer programming, all without needing any coding experience.

✍️ Part B: Fill in the Blanks
Complete the following paragraph using the words: algorithm, comparison, array, sorted, swap.
When sorting an _______ of playing cards, the _______ involves repeated _______ to determine the correct order. If two cards are in the wrong order, a _______ is performed to place them correctly. The process continues until the entire _______ is _______.
Answer:
When sorting an array of playing cards, the algorithm involves repeated comparison to determine the correct order. If two cards are in the wrong order, a swap is performed to place them correctly. The process continues until the entire array is sorted.
