Quick Sort using C

Quick sort or quicksort (sometimes called partition-exchange sort) is an efficient and very fast sorting algorithm for internal sorting, serving as a systematic method for placing the elements of an array in order. When implemented well, it can be about two or three times faster than its main competitors, merge sort and heapsort. In efficient […]

Bubble Sort using C

Bubble sort is one of the most popular sorting methods. It can be treated as a selection sort because it is based on successively selecting the smallest element, second smallest element and so on. In order to find the successive smallest elements this process relies heavily on the exchange of the adjacent elements and swaps […]

Straight Selection Sort using C

Selection sorting refers to a class of algorithms for sorting a list of items using comparisons. These algorithms select successively smaller or larger items from the list and add them to the output sequence. This is an improvement of the Simple Selection Sort and instead of replacing the selected element by a unique value in […]

Simple Selection Sort using C

The simplest possible technique based on the principle of repeated selection makes use of “n” passes over an array elements. In the i-th pass, the i-th smallest element is selected from the given array and it is placed in the i-th position of a separate output array. The already selected element is not selected next […]

Shell Sort using C

This method makes repeated use of straight insertion or shuttle sort. An array with n elements, in each pass, an increment is chosen. The increment must be less than n and the increment progressively should be smaller and the last increment must be equal to 1. Please find detail information on Shell Sort https://en.wikipedia.org/wiki/Shellsort

Straight Insertion Sort using C

Insertion sort is a simple sorting algorithm that builds the final sorted array (or list) one item at a time. More details can be found here at https://en.wikipedia.org/wiki/Insertion_sort Let’s say we have an array a, so at each i-th pass, a[i] is successively compared with a[i-1], a[i-2], etc. until an element smaller than a[i] is […]

Shuttle Sort using C

In Shuttle Sort technique for n elements in an array a, it requires n-1 passes. When i-th pass(1<=i<=n) begins, the first i elements, i.e., elements a[0] to a[i-1] have been sorted and these occupy the first i positions of the array. To insert (i+1)th element, a[i] is compared with a[i-1] and if the value of […]

Queue using Linked List in C Program

A queue like a stack is another special type of ordered list. In queue insertion operations are permitted at one end of the list and deletion operations are performed at the other end of the list. The end where insertion operations are performed is called rear and the end where deletion operations are performed is […]

Stack using Linked List in C Program

Stack is a special kind of linear list. Linear list is an ordered collection of a number of items of the same type. Two operations are performed frequently from linear list – insertion and deletion. A stack is a linear list where all insertions and deletions happen at one end of the list. A stack […]
