Have you tried the Standard qsort, and measured it to be inadequate
for your setup? Maybe a mergesort or a heapsort might be better?

qsort doesn't work directly on linked lists. It's for arrays.

qsort might be implemented as merge sort or heap sort.

Whether browsing forward or backward can be done using a singly linked list. Is there any specific case where a doubly linked list is needed? For people who say that singly linked list allows traversal only in one direction, I would say that using appropriate loops/recursion, traversal in opposite direction is also possible. Then why the need for doubly linked list? --

Heres the story, I have to create a doubly linked list for class, and i have no clue on how to do it, i can barely create a single linked list. It has to have both a head and a tail pointer, and each node in the list must contain two pointers, one pointing forward and one pointing backwards. Each node in the list will contain 3 data values: an item ID (string), a quantity (integer) and a price (float). The ID will contain only letters and...

Hi, I am working on a program that simulates one of the elements of ATM. The simulation stores events which occurs every some milliseconds for a certain amount of time. Every time that an event is stored in a double linked list, the whole list is sorted for the next round. My problem appears when subjecting the program to heavy load, that is, when I run the simulation for more than 10,000 miliseconds (every event occurs in...

Hi there, I'm a novice C programmer working with a series of large (30,000 x 30,000) sparse matrices on a Linux system using the GCC compiler. To represent and store these matrices, I'd like to implement the sparse matrices as a doubly-linked list, in which each non-zero cell is stored roughly as follows: int rownum int colnum

This program follows from the section 6.5 of K&R2 where authors created a doubly-linked list using a binary-tree based approach. The only thing I have rewritten myself is the getword function. I am using it because there are many concepts involved in this program that I want to understand like: 1.) degree of efficiency of this program as compared to sort using hash-table based approach. 2.) Keeping the program well structured so...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers.
