</html><description>Hello, everyone! Today, we will learn about one of the important algorithms in coding tests using JavaScript, the Extended Euclidean Algorithm. In this course, we will provide the concept of the Extended Euclidean Algorithm, the problem-solving process using it, and practical code examples. 1. Problem Description We will define the problem as follows. Given two &hellip; &#xB354; &#xBCF4;&#xAE30; ""</description></oembed>
