Welcome to the Week 17 of our daily challenges!
Each day you'll get to solve a challenge whose difficulty level increases as the week progresses!
To solve the final challenge, you're given an entire weekend.
There are 5 challenges in total!!
Challenge score decreases by 10% every day.

Tie-breaking rule: 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.

Note: Any illegal submission will be deleted from leaderboard without warning.

The other scoring rules remain the same. You can read them here.

Are you going to be the next Weekly champion?
