While Java provides several ways to handle string manipulation, regular expressions (regex) offer a powerful and efficient tool for such tasks. Problem Statement  The maximum numeric value is extracted from an alphanumeric ... Read More

Finding close matches to a string from a list of words is a common problem in string manipulation and pattern recognition. This article demonstrates two effective approaches for solving this problem in Java. The first approach utilizes string encoding to identify similar patterns, while the second approach leverages the Levenshtein ... Read More

In this article, we will learn to count the total number of minimum required rotations to get the original string in Java. We can solve the problem by getting the rotations substrings of the original string or concatenating the original string to itself.  Problem statement We have given string str ... Read More

A heterogram is a string where each letter appears only once, with no repeated characters. This property makes it unique and an interesting problem to solve in Java. In this article, we will learn to determine whether a given string is a heterogram using a frequency-based approach and introduce an ... Read More

In this article, we will learn Pigeonhole Sort in Java, a sorting algorithm designed for arrays with a small range of integer values. It organizes elements into "pigeonholes" based on their values and then reconstructs the sorted array. We’ll discuss two approaches: a basic method using arrays and an optimized ... Read More
