suggestions for pattern diff?

Question

Hi everyone!

I currently pass all the tests except the ones with pattern_diff_ since I can't manage to remove the images that don't check the conditions. I know that the consecutive lines of pixels have to be different and that I should make sure every pixel with index x in a line is different from the pixels with index x-1, x and x+1 of the following line. I wrote a function that checks that condition but apparently it doesn't work. Since I work with trees I even try to build it while checking the condition to avoid making not valid images but it still returns all the possible combinations.

Can someone maybe give me some other ideas to approach the problem so that I can try to rethink it in a different way?

Thanks!!!

Answer 1

While building the tree you should try to build the image already in perfect state. When the image is built in this way there are some cases where it will be incomplete, because not enough colors will be available. In that case the branch should stop there, and that "cut" branch should not be considered as a valid image.
