Sorry, but I don't get your point "I should suggest trying to implement the day getting by hand" can you more elaborate on this point, I think this is more exciting for me to implement something new.

@sukhpreetsekhon I meant that I do not like the way you have used the Date class to get the day. That detail means your algorithm provides no new knowledge tactic for problem solving, and we of course do not want that. I want you to create a function to find the day which will not exploit native behavior. Like for finding the day, you could calculate the number of days passed from a known date, and calculate the day using that.

Thanks, I have already built such a method in my open-source npm package (SolverJs). Can you like to see it and make some suggestions? and my name is @suryapratapsinghsuryavanshi. 😄

@suryapratapsinghsuryavanshi I think you did not understand what I meant. I said the idea of finding the day was good, but implementing it using the Date Class is sort of cheating, and people who see that algorithm do not learn anything new. I wanted you to implement finding the day yourself, and not using the Date class.

Sorry, I guess this time I've implemented what you wanted.
