Longest Substring of A that can be changed to Substring of B in at most T cost
In this problem, we will find the longest substring of A to convert it to a substring of B starting from the same index in less than T cost. We will use the binary search algorithm to find the maximum length of the substring which follows the given condition. However, the naïve approach to solving the problem is to find all substrings following the conditions in the problem statement and take the substring with maximum length. Problem statement − We have given a string A and B of length N. Also, we have given a total cost, ‘T’. The ...
Read MoreLexicographic rank of a string among all its substrings
String manipulation is an essential topic in computer science that involves operations such as concatenation, substring, reversing, and more. One interesting problem related to string manipulation is to find the lexicographic rank of a string among all its substrings. In this article, we will discuss an algorithm to solve this problem using recursion and backtracking. Problem Statement Given a string S of length N, we have to find the lexicographic rank of S among all its substrings. The lexicographic rank is defined as the position of a string in the lexicographically sorted list of all its substrings. Approach We can ...
Read MoreLexicographic rank of a Binary String
In this article, we will explore an intriguing problem that involves binary strings and lexicographic ordering. Our task is to find the lexicographic rank of a given binary string. We'll demonstrate our solution, a popular programming language known for its efficiency and flexibility. Understanding Lexicographic Ordering Lexicographic or lexicographical ordering (also known as alphabetical or dictionary ordering) refers to the arrangement of words based on the alphabetical order of their component letters. Problem Statement Given a binary string, we need to determine its lexicographic rank among all its permutations. The lexicographic rank of a string is its position in the ...
Read MoreLengths of maximized partitions of a string such that each character of the string appears in one substring
In this article, we will explore the problem of finding the lengths of maximized partitions of a string with unique characters. We will first understand the problem statement and then investigate both the naive and efficient approaches to solve this problem, along with their respective algorithms and time complexities. Lastly, we will implement the solution. Problem Statement Given a string, partition the string into as many substrings as possible such that each character of the string appears in only one substring. Return the lengths of these maximized partitions. Naive Approach The naive approach is to iterate through the string, ...
Read MoreLength of longest substring to be deleted to make a string equal to another string
In this article, we will discuss the problem of finding the length of the longest substring that needs to be deleted to make one string equal to another. We will first understand the problem statement and then explore both the naive and efficient approaches to solve this problem, along with their respective algorithms and time complexities. Lastly, we will implement the solution. Problem Statement Given two strings, A and B, determine the length of the longest substring that needs to be deleted from string A to make it equal to string B. Naive Approach The naive approach is to generate ...
Read MoreLength of longest prefix anagram which are common in given two strings
In this article, we delve into a fascinating problem in the realm of string manipulation and anagram analysis. Specifically, we'll be finding the length of the longest prefix anagram that is common to two given strings. Our solution leverages C, C++, Java and Python, a powerful and versatile programming languages beloved by software developers. Understanding Anagrams An anagram is a word or phrase formed by rearranging the letters of a different word or phrase, typically using all the original letters exactly once. For instance, the words 'listen' and 'silent' are anagrams of each other. Problem Statement Given two strings, we ...
Read MoreHow to Run Your First Spring Boot Application in IntelliJ?
IntelliJ is simple and very convenient to use in building reliable as well as scalable systems with Spring Boot, and it has become tremendously famous among Java developers. It also offers a convention-over-configuration approach by obviating the demand for bulky boilerplate code and enabling designers to concentrate on business logic. This potent web tool aims in generating a basic project structure with the necessary dependencies. The second method focuses on importing a pre-existing Spring Boot project into IntelliJ IDEA so that one can work on an existing codebase. To execute this code in IntelliJ one must ensure that they have ...
Read MoreHow to Run Your First Spring Boot Application in Spring Tool Suite?
Spring boot facilitate the simple way to create robust, scalable, as well as production-ready applications, by doing this they have revolutionized the development of Java applications. The "convention over configuration" philosophy, which is embraced by Spring Boot as a component of the larger Spring ecosystem, lessens the effort of manual setup and enables developers to concentrate on business logic rather than boilerplate code. The Spring Boot experience is considerably more effective when combined with Spring Tool Suite (STS), a specialized IDE created for Spring development. To execute this code in Spring Tool Suite one must ensure that they have the following prerequisites before we ...
Read MoreGenerate a sequence determined by the characters of a given string
In this article, we'll discuss an engaging problem related to strings and sequences. The problem statement is "Generate a sequence determined by the characters of a given string". This problem is an excellent way to enhance your skills in string manipulation and sequence generation. Problem Statement Given a string, the task is to generate a sequence where each character of the string is replaced by its position in the English alphabet. Solution Approach Our approach to this problem is straightforward. We will iterate over the string and for each character, we will calculate its position in the English alphabet. The ...
Read MoreFlip the String by Either Swapping given Characters or Rotating it Horizontally for Q Queries
Flip the String by either swapping given characters or rotating it horizontally for Q queries is a fascinating problem that involves manipulating a string based on a series of queries. In this tutorial, we delve into this problem and provide a solution using C++. The problem statement revolves around a string of characters and a set of queries, each containing instructions to swap specific characters or perform a horizontal rotation. Our objective is to determine the final configuration of the string after applying all the queries. Through this tutorial, we will explore the intricacies of the ...
