In the quest to combat the COVID-19 pandemic, accurate and accessible information about ICMR-approved test centers is crucial which can be done with the help of a python package called folium. This article explores how to leverage the power of Python and the folium package to plot these test centers on Google Maps. By combining geospatial data with interactive mapping capabilities, we empower individuals to easily locate nearby testing facilities. With a step-by-step guide, we demonstrate how to harness the folium package to create dynamic maps, customize markers, and provide informative pop-ups. By enabling the visualization of ICMR-approved test ... Read More

ASCII (American Standard Code for Information Interchange), is a character encoding system that represents every character as a unique 7-bit binary code i.e. ASCII values are a numerical representation of characters. The ASCII values are 7-bit binary codes that range from 0 to 127. For Example, the ASCII code for a space character is 32, and for digit ‘1’ ASCII code is 49 and similarly ASCII codes are assigned to each character which is represented in an ASCII table. In Python, the ASCII code of a character can be computed using a predefined function ord(), which takes a character as ... Read More

Binomial expansion is a mathematical formula used to expand the expressions of the form (a+b)^n, where n is a positive integer and a and b can be any real or complex numbers. The expansion gives the coefficients of the terms in the expansion. A binomial expansion can be represented as $$\mathrm{(a+b)^n= ^nC_0a^nb^0+ ^nC_1a^{n-1}b^1 + ^nCa^{n-2}b^2+...+ ^nC_ra^{n-r}b^r+...+ ^nC_na^0b^n}$$ where $\mathrm{^nC_r}$ are the binomial coefficients and is given by $\mathrm{^nC_r=\frac{n!}{r!\times(n−r)!}}$ where n! is the factorial of n The expansion can be used for calculating all the binomial terms using the formula above and putting it into the expansion equation. Problem ... 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

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

The circumference of a circle can be defined as the outer boundary of the circle. It is the perimeter of a circle. Each point around a circle follows certain properties as follows − Point (x, y) lying inside the circle such that, $\mathrm{x^2 + y^2 < R^2}$ Point (x, y) lying on the circle such that, $\mathrm{x^2 + y^2 = R^2}$ Point (x, y) lying outside the circle such that, $\mathrm{x^2 + y^2 > R^2}$ where R = radius of the circle. Problem Statement Given a string S representing a sequence of moves (L, R, U, D) and ... Read More

In computer programming, comments are text written with the source code but ignored by the compiler or interpreter. They are used to provide readability of code by describing the code and its functionality for someone who is reading the code other than a compiler or interpreter. They are not executed and do not affect the functionality of the overall program, they are just for programmer guidance. Each programming language has a different syntax to represent comments. Here are a few examples − C/C++ − In C or C++, single-lined comments begin with ‘//’ and multi-liner comments are enclosed in ... Read More

The pairwise product of a set X = {a, b, c} can be defined as the sum of the product of all possible set pairs. The pairs of the set are, Y = {a * a, a * b, a *c, b * b, b * c, c * c}, where the product is commutative. Thus, the pairwise product of set X is the summation of elements of set Y i.e. aa + ab + ac + bb + bc + cc. In mathematical terms, the sum of possible pair products can be depicted as, $$\mathrm{\displaystyle\sum\limits_{i=1, j=i}^{i\leq n, j\leq n}\:(i, ... Read More

Input and output are the vital components of all the programming languages. Same is the case with Java. User input is very crucial for creating dynamic and interactive applications. Usually the input is a single value but we can also take input from the user separated by space. This article deals with how to take input from the user separated by spaces in Java. Ways to Take Input From User Separated By Space in Java There are 2 ways by which we can take the input from the user separated by space. They are as follows- ... Read More
