By leveraging the concept of water flow in a physical landscape, the Watershed algorithm has emerged as a powerful tool for accurately identifying boundaries and separating objects in an image. Together, we will dive into the step−by−step process, from preprocessing the ... Read More
Modifying an array of strings by replacing characters repeating in the same or remaining strings is a common problem in programming. It can be solved using hash tables, sets, arrays etc. The aim is to improve the time and space requirements while providing the same functionality. This problem can be encountered in many real-life scenarios, such as processing large text or cleaning up datasets with duplicates. Problem Statement Given an input string array arr[] containing lowercase and uppercase characters. The goal is to modify the array by removing characters from the strings which are repeating in the same string or ... Read More
Python is a versatile and powerful programming language known for its simplicity and readability. One of the key features that make Python stand out is its support for lambda functions, which are anonymous functions that can be created on the fly. Lambda functions offer a concise and elegant way to define small, one−line functions without the need for a formal function definition. These functions can be used in various scenarios to enhance code readability and maintainability. In this tutorial, we will delve into the fascinating world of lambda functions in Python and explore how to incorporate if, else, and elif ... Read More
Logic gates are the basic building block of a digital circuit. They take in one or two binary inputs and return a binary output. Since, using the term binary, the output and input can either be 0 or 1 or it can be said as “false” and “true” or “low” and “high”. There are 3 basic logic gates − AND Gate AND gate has two or more inputs and one output. It produces a high output if all inputs are high. The truth table for a two-input AND gate is given below − Input 1 Input 2 Output ... Read More
