Data Structure Sorting Methods

7 Questions

The elements are swapped

$n-1$ times

Elements are compared in pairs at a time

Moving the largest element to the leftmost position

Insertion sort

Into two parts: sorted part on the right, unsorted part on the left

Merge sort splits the list into two halves recursively

Study Notes

Sorting is the process of arranging elements of a list in a particular order (ascending or descending) based on the key value of each record.
There are different sorting methods, each with different running times (complexities).

Internal Sort: Does not require external memory for sorting, useful for sorting fewer elements.
- Examples: Bubble Sort, Quick Sort, Selection Sort, Insertion Sort
External Sort: Requires external memory for sorting, useful for sorting large numbers of elements.
- Examples: Merge Sort, Radix Sort

A simple sorting algorithm that compares all elements one by one and sorts them based on their values.
Not suitable for large data sets due to average and worst-case complexities of O(n2), where n is the number of items.

An efficient sorting method for large lists, using a divide and conquer strategy.
Divides the list into two smaller lists, then recursively sorts the sublists.
Pivot element is used to divide the list, and elements are swapped accordingly.

A simple sorting algorithm that is an in-place comparison-based algorithm.
Divides the list into two parts: the sorted part (at the left end) and the unsorted part (at the right end).
Selects the smallest element from the unsorted array and swaps it with the leftmost element, repeating the process until the entire list is sorted.
