In this lecture, we will understand Counting Sort, a non-comparison based sorting algorithm that works efficiently when the range of input values is small.
Unlike algorithms like Quick Sort or Merge Sort, Counting Sort does not use comparisons and can achieve linear time complexity under the right conditions.
Topics covered in this video:
What is Counting Sort?
Why Counting Sort is different from comparison-based sorting
Working principle of Counting Sort
Frequency/count array concept
Step-by-step example of Counting Sort
Time and space complexity analysis
When to use Counting Sort
Limitations of Counting Sort
This lecture will help you understand sorting fundamentals and choose the right algorithm based on constraints, which is very important for DSA problems and interviews.
This video is part of my Java + DSA course by ShashCode, designed for:
DSA beginners
College students
Placement & interview preparation
Strong algorithmic foundations
👉 Watch till the end to clearly understand why Counting Sort can be faster than O(n log n) algorithms.
