C String Sorting Methods

There are several methods for sorting strings in C language, some commonly used methods include the following:

1. Bubble sort: Compare neighboring strings, swap positions if they are in the wrong order, and repeat the process until all strings are sorted.
2. Selection sort: Find the smallest (or largest) string in the unsorted portion, swap it with the first string in the unsorted portion, and repeat until all strings are sorted.
3. Insertion sort: Taking the first element of the unsorted portion and inserting it into the appropriate position within the sorted portion, repeating this process until all elements are in order.
4. Quick sort: Choose a pivot string, place strings smaller than the pivot string to the left of it, and strings larger than the pivot string to the right of it, then quick sort the strings on the left and right sides again, and finally merge to get a sorted string sequence.
5. Merge sort involves continuously dividing a string sequence into smaller sub-sequences until each sub-sequence contains only one element, and then merging the sub-sequences in pairs until finally obtaining a sorted string sequence.

The above are several common methods for sorting strings. Choose the appropriate sorting method based on actual needs and performance requirements.
