Counting Sort in Java

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, 2, 1, 0, … Read more

Java Program to Implement Heap Sort

This is the Java Program to Implement Heap Sort Using Library Functions. Problem Description Given an array of integers, sort the array using heapsort algorithm, as built into the library. Problem Solution The idea is to create a priority queue of the array elements. A priority queue is a min-heap. Extract the elements from the … Read more

Java Program to Implement Merge Sort

What is Merge Sort? Merge Sort in Java is a divide and conquer-based sorting algorithm. In this sorting algorithm the unsorted array keeps on dividing into two halves until the array is either empty or contains only one element, which is the base case of Merge Sort, and then the halves are combined/Merged in sorted … Read more

Java Program to Implement Insertion Sort

What is Insertion Sort? Insertion sort is a simple sorting algorithm that builds the final sorted array (or list) one item at a time. It is much less efficient on large lists than more advanced algorithms such as quicksort, heapsort, or merge sort. Problem Description Create a Java program to perform an insertion sort and … Read more

Java Program to Implement Selection Sort

What is Selection Sort? Selection sort is a sorting algorithm, specifically an in-place comparison sort. It has O(n2) time complexity, making it inefficient on large lists, and generally performs worse than the similar insertion sort. Selection sort in Java is noted for its simplicity and has performance advantages over more complicated algorithms in certain situations, … Read more
