We can find a online editor that not only allows us to run the code but to also visualise what’s going on. Giving the ingredients pain and effort a value so it all compiles and after doing some reading, we see that there is meant to be some output
After re-reading the documents, it appears as though the bowl values need to line up to ASCII values, with the last value in the bowl being printed first. Through some trial and error, we can somewhat quickly see what values pain and effort need to be to start making this happen
