Lengths 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 plot multiple graphs in Matplotlib?
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()Output
Read MoreHow to align text to the left in Tkinter Label?
Tkinter Label widget can be aligned using the anchor attributes. In order to calculate the accommodate spacing and alignment of the widget, anchor would help in a better way. Anchor provides several options such as N, W, S, E, NW, NE. SW, SE which can be defined in the pack manager itself.ExampleIn the following example, we will align the Label text of an application to the left by adding the anchor attribute towards “w” direction.#Import the required library from tkinter import* #Create an instance of tkinter frame win= Tk() #Set the geometry win.geometry("750x250") #Create a Label Widget Label(win, text= "New ...
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 ...
Read MoreFlip all 0s in given Binary Strings K times with different Neighbours
The task of flipping 0s in a binary string while considering their adjacent characters has practical applications in various domains. In this tutorial, we delve into the problem of modifying a given binary string by repeatedly flipping the 0s that have different adjacent characters. Specifically, we aim to solve this problem within the context of C++ programming. The solution involves iteratively scanning the string and applying the necessary flips based on the provided logic. By leveraging the string manipulation capabilities, we can efficiently transform the binary string by flipping 0s K times, ensuring that each flip adheres to the ...
Read MoreFind two unique Palindrome Strings using given String characters
In this problem, we will construct two palindromic strings using the given string’s characters. We can use the character’s frequency to solve the problem. We can construct two new palindromic strings only if both characters’ frequencies are even or if any characters have an even frequency and others have an odd frequency. Problem statement − We have given a string alpha containing two different characters and a size equal to N. We need to construct two palindromic strings using the characters of the alpha, which are not the same as the given string alpha. Sample Examples After incrementing each character ...
