Counting sort

The counting sort flow starts by calculating the minimum and the maximum element in the array. Based on the computed minimum and maximum, the algorithm defines a new array that will be used to count the unsorted elements by using the element as the index. Furthermore, this new array is modified in such a way that each element at each index stores the sum of previous counts. Finally, the sorted array is obtained from this new array.

The time complexity cases are as follows: best case O(n + k), average case O(n + k), worst case O(n + k)

The space complexity case is as follows: worst case O(k)

k is the number of possible values in the range. n is the number of elements to be sorted.

Let's consider a quick example. The initial array ...
