Unfortunately, since there are so many emails in my Gmail inbox, I was unable to see the email promptly. I took the challenge on 29th, a week after the challenge’s close.
I was unable to finish that on time. Since I was just thinking about the awful fact that I missed the competition totally.
I did not hand in the solution on time, but I will try solving the problem and post my solution later.
I tried to clean my mailbox and unsubscribed many irrelevant email subscriptions. Also, I have made up my mind to check my email more carefully in the future so that there won’t be any missed important emails.
