👉 Doline is a type of mathematical function that represents a line segment. It's often used in geometry and trigonometry to represent the length of a line segment or the direction of a vector. In terms of programming, Doline can be defined as a 1-dimensional array representing a line segment with its endpoints at (x0, y0) and (x1, y1). The function that represents this line segment is typically denoted by `doline(x0, y0,
