The problem is pretty simple and usually follows these steps:
1. Take the position of the starting point and the boundary color.
2. Decide wether you want to go in 4 directions (N, S, W, E) or 8 directions (N, S, W, E, NW, NE, SW, SE).
2. Decide whether you want to go in 4 directions (N, S, W, E) or 8 directions (N, S, W, E, NW, NE, SW, SE).
3. Choose a fill color.
4. Travel in those directions.
5. If the pixel you land on is not the fill color or the boundary color, replace it with the fill color.

From the given code you can see that for any pixel that you land on, you first check whether it can be changed to the fill_color and then you do so
for its neighbours till all the pixels within the boundary have been checked.
