Welcome to the Week 7 of our daily challenges! Each day you'll get to solve a challenge whose difficulty level increases as the week progresses!
The problems will remain open for submissions from the day they are posted to Sunday. So, a problem posted on Monday will be live for 7 days, a problem posted on Tuesday will be live for 6 days, and so on.
There are 5 challenges in total!!
Tie-breaking rule is little different for this contest. For each challenge, we calculate your solved time, t
t = submit - open
where submit is the time you submitted the solution, and open is the time you opened the challenge. This way, you do not have to worry about solving the challenge as soon as it becomes available.
