Teaching I'm an ex-pat teacher teaching AP Calculus and AP Statistics at a large International School in Sarajevo, Bosnia and Herzegovina. This is my fourth country in the last nine years. I've always been interested in technology ever sinc…

Formula 1 From the unit circle sin^2x +cos^2 x=1 That's pretty intuitive. Formula 2 divide both sides by cos^2x to get, sin^2x/cos^2x= 1/cos^2x sin/cos=tan and so sin^2x/cos ^2x= tan ^2x. 1/cos^2x=sec^2x so, tan^2x +1= sec^2x. Formula 3 div…

Introduction In this article, I’ll talk about a n-th primitive root of unity used in number theory in math, especially in the context of a finite field. I’m a software engineer, not a mathematician so I want to see this in the eyes of softw…

Introduction Hello Reader, In this blog we'll be looking into the Internal working of Data Structure : HashTable, HashTables are implemented in almost all the Object Oriented Programming Languages, li…

About half a year after I started my master's study in a new city (thus it was in 2015), I began attending special meetings that are called «career day», which were held in my university several times…

Cryptography has been around for centuries, and it has undergone a significant evolution over time. In its early days, cryptography was used primarily for military purposes, but today it is used in a …

In your python terminal try executing this >>> 0.1+0.2 == 0.3 Weird is it not? The answer should have been True. Every programmer would have faced this issue at some point in time. If they have not, they are bound to face it in the future.…

Problem statement Given an integer n, return the decimal value of the binary string formed by concatenating the binary representations of 1 to n in order, modulo 10^9 + 7. Example 1 Input: n = 1 Outpu…

Problem statement Given an integer array nums of size n, return the minimum number of moves required to make all array elements equal. In one move, you can increment or decrement an element of the arr…

Today I'm gonna talk about how computers actually encrypt data and also decrypt data. There are a lot of encryption and decryption algorithm are there but for our learning purposes we will talk about the easy one which is Affine code funct…
