This is the Java Program to Implement Heap Sort on an Array of n Elements. Problem Description Given an array of integers, sort the array using heap sort algorithm. Problem Solution The idea is to create a max heap of the array elements. Then, obtain the maximum element from the heap, interchange it with the … Read more
This is a Java Program to Sort Names in an Alphabetical Order. Enter size of array and then enter all the names in that array. Now with the help of compareTo operator we can easily sort names in Alphabetical Order. Here is the source code of the Java Program to Sort Names in an Alphabetical … Read more
This is a Java Program to Sort the Array in Descending Order. Enter size of array and then enter all the elements of that array. Now with the help of for loop and temp variable we sort the array in descending order. Here is the source code of the Java Program to Sort the Array … Read more
Problem Description Write a Java Program to Sort the Array in an Ascending Order. Problem Solution Enter the size of the array, and then enter all the elements of that array. Then, the program uses a for loop to sort the array in ascending order by comparing each element of the array with all the … Read more
This is a Java Program to Find if a given Integer X appears more than N/2 times in a Sorted Array of N Integers. Enter size of array and then enter all the elements of that array. Now enter the element you want to check. With the help of for loop now we check if … Read more
This is a java program to solve set cover problem. The set covering problem (SCP) is a classical question in combinatorics, computer science and complexity theory.Given a set of elements \{1,2,…,m\} (called the universe) and a set S of n sets whose union equals the universe, the set cover problem is to identify the smallest … Read more

This is a java program to implement Aho-Corasick Algorithm. It is a kind of dictionary-matching algorithm that locates elements of a finite set of strings (the “dictionary”) within an input text. It matches all patterns simultaneously. The complexity of the algorithm is linear in the length of the patterns plus the length of the searched … Read more
