C Sorting

This lesson is part of C · All levels

Summary

The sequence composes data from the smallest to the largest value or vice versa so that it is easier to search and appear. Basic algorithms such as bubble sort, selection sort, and insertion sort are easy to understand despite their complexity, whereas quicksort and mergesort are much faster for big data with average. The algorithm's choice takes into account the size of the data, the need for stability, and the availability of memory.

Key points

Bubble sort exchanges adjacent elements when the wrong order is made and repeats until there is no exchange.
Selection sort selects the smallest element of each pass and puts it in the correct position.
Insertion sort inserts elements into the front that are sorted and efficient for near-order data.
Stable sort maintains a relative order of elements with the same value, important for pairing data.
Quicksort partitions the array and then sequences each part recursively.
