1. The code starts by importing the necessary libraries. We import `matplotlib.pyplot` as `plt` to handle the plotting of the line. 2. The `dda_algorithm` function takes four parameters: `x1`, `y1`, ...

In its simplest implementation for linear cases such as lines, the DDA algorithm interpolates values in interval by computing for each xi the equations xi = xi−1 + 1, yi = yi−1 + m, where m is the ...
