1. Core idea of sorting
- Sorting means arranging a collection of elements in a particular order.
- Numbers can be sorted in ascending or descending order.
- Strings can be sorted alphabetically or by length.
2. Bubble Sort
- Bubble sort compares adjacent elements repeatedly and swaps them if they are unordered.
- For a list with n elements, bubble sort makes n-1 passes.
- After each pass, the largest element reaches its correct position at the end.
3. Selection Sort
- Selection sort divides the list into a sorted left part and an unsorted right part.
- Initially, the left part is empty and the right part contains all elements.
- In each pass, the smallest element in the unsorted part is found.
4. Insertion Sort
- Insertion sort divides the list into sorted and unsorted parts.
- Each unsorted element is inserted into its correct position in the sorted part.
- The sorted list is traversed backward to find the insertion position.
