Counting sort is a sorting algorithm that sorts the elements of an array by counting the number of occurrences of each unique element in the array and sorting them according to the keys that are small integers. In this tutorial, you will understand the w
Compute theCarray as is done in counting sort. The number of integers in the range [a..b]isC[b]−C[a−1], where we interpretC[−1] as 0.

Counting Sort is a linear sorting algorithm with asymptotic complexity O(n+k). In this post we will discuss the counting sort algorithm with pseudocode, implementation in C Java
But it's pretty simple to extend the algorithm to handle any sort of range of integers. Give it a try. :) Complexity Counting sort takes O(n+k)O(n+k) time and O(n+k)O(n+k) space, where nn is the number of items we're sorting and kk is the number of possible values. ...

No sorting algorithm can sort n elements in better than O(n log n) time if comparing elements. However, there are other ways of sorting elements if we know some information about those elements in advance
Counting sort is basically a linear time sorting algorithm. It sorts given array having integer elements ranging from 0 to K (where 'K' is upper limit of integer which can be present in input array). Counting sort can only be applied to positive integers and yields running time of 螛 (n...
Counting Sort in Java is a sorting algorithm that counts the frequency of each element and then sorts the input array in increasing order. It is efficient for sorting integers or other values with a small range. Example: 1. Let’s say we have an array of numbers, like {4, 1, 3, 4...
