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 More
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 More
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 More
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 More
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 More
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 More
Introduction In the realm of Python programming, the calendar module serves as a flexible toolkit for overseeing date and time operations. Inside this module, the yeardayscalendar() strategy discreetly sparkles as a particular jewel. Not at all like conventional calendar functions, this strategy presents a new viewpoint by organizing days into weeks, advertising an elective way to comprehend the entry of time. In this article, we dive into the profundities of the yeardayscalendar() strategy, revealing its focal points, applications, and the special experiences it offers when managing calendars from a week-by-week perspective. Exploring the Module `yeardayscalendar()` Method? The Python calendar module, known ... Read More
Algorithm and Pseudocode are the two related terms in computer programming. The basic difference between algorithm and pseudocode is that an algorithm is a step-by-step procedure developed to solve a problem, while a pseudocode is a technique of developing an algorithm. In this article, we will discuss the other important differences between an algorithm and a pseudocode. Let's start with some basic concepts of algorithm and pseudocode. What is an Algorithm? A sequence of steps to solve a given problem is called as algorithm. Thus, an algorithm is a step-by-step procedure developed for solving a given problem. An ... Read More
To plot multiple graphs in matplotlib, we will use the following steps −StepsCreate x, y1 and y2 data points using numpy.Add a subplot to the current figure at index 1.Plot curve 1 using x and y1.Add a subplot to the current figure at index 2.Plot curve 2 using x and y2.To display the figure, use show() method.Exampleimport numpy as np from matplotlib import pyplot as plt plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True x = np.linspace(-2, 2, 10) y1 = np.sin(x) y2 = np.cos(x) plt.subplot(211) plt.plot(y1) plt.subplot(212) plt.plot(y2) plt.show()OutputRead More
The operating system is needed to design and implement because without proper design and implementation any system cannot work properly, for every aspect or for any development a proper design and implementation should be necessary so that it can work in good manner and we can easily debug if any failures occur.So, design and implementation is a necessary part of an operating system and this technique can be used by every user who uses a computer.There are different types of techniques to design and implement the operating system.Design goalsMechanismImplementationLet us discuss each technique in detail.Design goalsLet us understand the features ...
