NumPy is a powerful library in Python for scientific computing, particularly for dealing with arrays and matrices. One of the lesser-known features of NumPy is its ability to generate arrays of dates. In this article, we will explore how to use NumPy to display all the dates for a particular month. Installation Before we start, let's make sure that NumPy is installed on our system. You can install it using pip by running the following command in your terminal or command prompt − pip install numpy Now that we have NumPy installed, let's start by importing it − import ...

In Python, the @dispatch decorator is used to overload functions with different signatures. This is a common pattern in object-oriented programming where multiple methods can have the same name, but different parameters or argument types. The @dispatch decorator allows you to write a single function with multiple implementations that will be chosen at runtime based on the arguments passed to the function. In Python, decorators are a powerful and widely used feature of the language. They allow you to modify or enhance the behaviour of functions, classes, or modules without changing their source code. One such decorator is the Dispatch ... Read More

PHP (Hypertext Preprocessor) is a widely-used open-source scripting language primarily designed for web development.

In PHP, you can pass variables by reference instead of by value using the ampersand (&) symbol. This allows you to modify the original variable within a function or method. There are primarily two ways to pass PHP variables by reference: Using the ampersand in the function/method declaration Using the ampersand when passing the variable to a function/method Using the Ampersand in the Function/Method Declaration In PHP, you can pass variables by reference using the ampersand symbol (&) in the ...

A monotonous substring is a contiguous substring of given string containing characters whose values are all strictly increasing or strictly decreasing. A monotonous substring is a string sequence that either strictly increases or strictly decreases in value. Method Dynamic Programming Backtracking Method 1: Dynamic Programming One technique is to apply dynamic programming to construct table of sub problems, here each item (i, j) in table denotes whether there exists a permutation of the substring S[i...j] that does not contain any monotonous substring. When i=j, the substring comprises only one character and is hence trivially monotonous. ... Read More

A binary string is made up of a succession of binary numbers, also known as bits, that are either 0 or 1. It is a method of encoding data that uses only two numbers for computer applications where data is stored and processed using electronic circuits that can only recognise two states. In computer programming, binary strings are frequently used to represent data in way that is simple for electronic circuits to handle, such as numbers, text, and images. Method Method 1. Dynamic Programming Method 2. Greedy Approach Method 1: Dynamic Programming To tackle this difficulty, we can employ ... Read More
