Counting Sort in Java1 min read

In this post, we will learn how to implement Counting Sort in java. First, we will start by understanding the Counting Sort algorithm.

Counting Sort Algorithm

Counting Sort Algorithm is an integer-based algorithm, non-comparison, and linear sorting algorithm. The counting sort algorithm sorts the elements in an array in a specific range. It is based on keys between the specific range.

Counting sort calculates the number of occurrences of objects and stores their key values. Then by adding the previous key elements, a new array is formed.

Before we begin, you need to have an idea on following:

Time Complexity of Counting Sort:

  • Best case:  0(n+k)
  • Average case:  0(n+k)
  • Worst case:  0(n+k)
