Flood fill (The Algorithms and Data Structures Interview Crash Course) no explanation of what to do

The title. There is no real explanation of what this algorithm should be doing, I had to take a look at the explanation to get an idea of what to do. The problem statement talks about rasterization in computer graphics, which is interesting. But nothing related to what the input is and what the output should be & what should be happening is explained at all in the problem statement.

Hi @Lucas3,

Thanks for highlighting the issue. Now we have updated the problem statement. Please have a look at Flood fill again.
