XNOR(Exclusive-NOR) gate is a digital logic gate that takes two inputs and gives one output. Its function is the logical complement of the Exclusive-OR (XOR) gate. The output is TRUE if both inputs are the same and FALSE if the inputs are different. The truth table of the XNOR gate is given below. A B Output 1 1 1 1 0 0 0 1 0 0 0 1 Problem Statement Given two numbers x and y. Find the XNOR of the two numbers. Sample Example 1 Input: x ... Read More
Introduction The text discusses the concept of a model in machine learning, its various forms, and how to evaluate its accuracy. It explains accuracy as a common evaluation metric used in machine learning and its limitations and provides an example of a Python program that demonstrates how to check the accuracy of a machine−learning model. The text also explains model accuracy as a performance metric for classification models and its usefulness in evaluating the overall performance of a model, while cautioning that other metrics may be more appropriate in certain situations. Model in Machine Learning In machine learning, ... Read More
Introduction Parsing and converting HTML files to XML format are regular activities that frequently emerge in the field of web development and data processing. In contrast to XML, which is a flexible markup language that makes data sharing and storage easier, HTML (Hypertext Markup Language) is the industry standard language for structuring and presenting information on the web. Data extraction, data transformation, and system compatibility are just a few uses for which it might be advantageous to convert HTML to XML. The importance of parsing and converting HTML to XML There are several reasons why parsing and converting ... Read More
Let x and y be two numbers. In this case, x is said to be a divisor of y if when y is divided by x it returns zero remainder. The maximum occurring divisor in an interval is the number that is a divisor of the maximum number of elements of that interval. Problem Statement Given an interval [a, b]. Find the maximum occurring divisor in the range including both a and b, except ‘1’. In case all divisors have equal occurrence, return 1. Sample Example 1 Input [2, 5] Output 2 Explanation − Divisors of 2 = ... Read More
Introduction Parsing datetime strings is a typical job when working with time and date information in Python. Traditional datetime forms, however, may not be sufficient as our requirement for precision grows. This is when nanoseconds enter the picture. Nanoseconds are the smallest unit of measurement of time, allowing for highly exact temporal computations. Parsing datetime strings with nanosecond precision is critical in various applications, including scientific investigations and financial data processing. Understanding Nanoseconds Nanoseconds, or one billionth of a second, provide fantastic clarity. It is crucial when timing precision is essential for example high−frequency trading or scientific ...

Ramanujan-Nagell Equation is an example of the exponential Diophantine equation. The diophantine equation is a polynomial equation with integer coefficients of two or more unknowns. Only integral solutions are required for the Diophantine equation. Ramanujan-Nagell Equation is an equation between a square number and a number that is seven less than the power of 2, where the power of 2 can only be a natural number. Ramanujan conjectured that the diophantine equation 2y - 7 = x2 has positive integral solutions and was later proved by Nagell. $$\mathrm{2y−7=x^2\:has\:x\epsilon\:Z_+:x=1, 3, 5, 11, 181}$$ Triangular Number − It counts objects arranged in ...
