Here is what I usually do.
wtf we basically said the same thing. does this mean I will get red one day?
Your coincidence is only once so the chance of you reaching red $$$ = \frac{1}{\text{number of your comments on cf}}$$$ which I think is pretty low.
oops idk why it is not displaying but just imagine the image of sad chud with "its over" text above
Usually, the brute force solutions to these problems are easy to write if you know recursive backtracking, so just write a brute force solution and generate a bunch of random testcases and find one that makes your original code produce a different answer.
