The complexity of counting Sort Technique Time Complexity: O(nr) Space Complexity: O(nr) Input A list of unsorted data: 2 5 6 2 3 10 3 6 7 8 Output Array after Sorting: 2 2 3 3 5 6 6 7 8 10 Algorithm countingSort(array, size) Input: An array of data, and the total number in the array Output: The sorted Array Begin.In the counting algorithm we dont compare element while sorting.it is often used as a subroutine in other sorting algorithm.It is used as a subroutine in another sorting algorithm for example radix sort.
![]() If we compare counting sort to bucket sort then we see that bucket sort requires a large amount of preallocated memory or linked list and dynamic array to hold the sets of items within each bucket, whereas counting sort instead stores a single number per bucket.

In Counting sort, we maintain an auxiliary array which drastically increases space requirement for the algorithm implementation. Then we count the number of occurrences of each array element from 0 to length-1 and assign it into the auxiliary array. This array is used again to retrieve the sorted version of the input array. Declare a new array of size max1 with value 0 Count each and every element in the array and increment its value at the corresponding index in the auxiliary array created Find cumulative sum is the auxiliary array we adding curr and prev frequency Now the cumulative value actually signifies the actual location of the element in the sorted input array Start iterating auxiliary array from 0 to max Put 0 at the corresponding index and reduce the count by 1, which will signify the second position of the element if it exists in the input array Now transfer array received in the above step in the actual input array.
