Image blurring is a fundamental technique in image processing that helps reduce noise and smooth out details. While traditional blur operations apply the same level of blurring uniformly across the entire image, adaptive blur takes it a step further by allowing variable blurring levels based on local image features. This enables us to preserve important details while effectively reducing noise and enhancing image quality. In this blog post, we'll explore how to implement adaptive blur using Python Wand, a powerful Python library for image manipulation. Python Wand provides a simple and intuitive interface for working with images and offers a ... Read More
Working with datasets involves identifying the smallest value in a specific column and updating it by adding a constant value (K). By implementing an optimized solution, we can efficiently perform this operation, which is crucial for data manipulation and analysis tasks. Working with tuple lists is a common way to represent structured data, where each tuple corresponds to a row and contains multiple elements or attributes. In this case, we will focus on a specific column of the tuple list and target the minimum element within that column. Understanding the Problem Before looking at the solution, let's establish a ...

Matrices are fundamental data structures in linear algebra and are extensively used in various scientific and mathematical computations. A matrix is a rectangular array of numbers arranged in rows and columns. It is commonly represented as a two-dimensional grid. However, there are scenarios where we may need to manipulate matrices with additional dimensions, either for data transformation or to perform advanced mathematical operations. Python, being a versatile programming language, offers a rich ecosystem of libraries that provide powerful tools for matrix operations. One such library is NumPy, which stands for Numerical Python. NumPy provides efficient and convenient tools for working ... Read More
Python Kivy is a powerful framework for building multi-touch applications, allowing developers to create interactive and intuitive user interfaces. One common requirement in many applications is the ability to detect and respond to double tap gestures on specific widgets. Setting up the Kivy Application Before diving into the implementation of double tap functionality, we need to set up a basic Kivy application. This step provides a foundation for the subsequent code implementation. We start by creating a new Python file and importing the necessary modules from the Kivy framework − from kivy.app import App from kivy.uix.boxlayout import BoxLayout from ... Read More
In the given problem statement we are required to find the common characters count for the given strings with the help of Javascript functionalities. So we will use basic Javascript to solve this problem. Understanding the problem The problem at hand is to find the common characters between the two given strings. So for solving this problem we will determine how many characters they have in common. For example suppose we have two strings like "abaac" and "baaaa" so in these two strings we can see there are 2 common characters which are 'a' and 'b'. So the ... Read More
In this problem, we need to convert one binary string to another binary string by flipping the characters of the string. We can hold any set bit and flip other bits, and we need to count the total operation to achieve another string by doing it. We can solve the problem based on the total number of ‘01’ and ‘10’ pairs in the given strings. Problem statement − We have given two strings named str1 and str2 of the same length containing ‘0’ and ‘1’ characters, representing the binary string. We need to convert the string str1 to str2 by ... Read More
In this problem, we need to find the reversible equal substring of maximum length from the start and end of the string. The problem is very similar to finding the palindromic string. We can start traversing the string and traverse the string until characters from the start and end match. Problem statement − We have given string str containing N characters. We need to check whether the string contains the reversible equal substring at the start and end of the string. If we find the substring according to the given condition, print the longest substring. Otherwise, print ‘false’ in the ... Read More
In this problem, we need to transform the string of a length greater than 2 into its abbreviation form. We can use the ‘length’ property of the string to count the total number of middle characters in the string, and we can first and last characters using the respected index value. Problem statement − We have given a string str of length greater than or equal to 2 and need to convert the string into its abbreviation form. The abbreviation form of the string is as shown here: first character + the total number of middle characters + last ... Read More
In this problem, we need to sort the given array of characters using a linked list. We can use bubble sort, selection sort, merger sort, etc. techniques to sort the array. Here, we will convert the array into the linked list first and then use the selection sort and bubble sort techniques to sort the array. Problem statement − We have given an array arr[] of length N. The array contains lowercase alphabetical characters. We need to sort the array using the linked list. Sample examples Input arr[] = {'e', 's', 'a', 'x', 'c', 'e', 'f', 'p', 'b', 'n', ... Read More
In this problem, we need to find the total number of rotations to get the same string. The naïve approach to solving the problem is that we can keep rotating the string. We can print the total number of required rotations if we find the same string. Also, other approaches take the substring from the string and make it equal to the original string. After that, we can get rotations using the substring length. Problem statement − We have given string str. We need to find the total number of rotations required to get the same string again. Sample examples ... Read More
