What to Focus On
- Sorting arranges data in a particular order.
- Numbers may be sorted ascending or descending.
- Strings may be sorted alphabetically or by length.
- Bubble sort compares adjacent elements.
- It swaps elements only when they are unordered.
- It makes n-1 passes for n elements.
- Selection sort makes n-1 passes.
- The left part is sorted and the right part is unsorted.
- The left list starts empty.
Common Mistakes to Avoid
Bubble sort stops as soon as the list becomes sorted, so it never needs all n - 1 passes.
Selection sort swaps many times in a single pass, just like bubble sort.
Selection sort and insertion sort both use the same idea because both divide the list into sorted and unsorted parts.
Memory Tips
Sorting means arranging a collection of elements in a particular order
Sorting can be ascending, descending, alphabetical, or length-based
A pass means one full iteration through the elements of a list
