Hello, Codeforces Community!

We are excited to announce the GoForGold Long Challenges—an innovative monthly contest series brought to you by Newton School of Technology. Starting on the second last Friday of every month, these challenges will run for 10 days, providing a fantastic platform to learn new things and hone your problem-solving skills.

As the Contest Coordinator, I invite you to share your creative problem ideas with us. This is a unique opportunity where you don't have to prepare a full-fledged problem—simply submit your idea. If your idea is accepted, you'll be rewarded with a cash prize!

Below is the reward structure based on the difficulty and corresponding Codeforces rating:

Difficulty CF Difficulty Rating Idea Reward (USD)
Cakewalk 800 — 1200 $6
Simple 1200 — 1600 $8
Easy 1600 — 1900 $10
Easy-Med 1900 — 2200 $15
Medium 2200 — 2400 $35
Med-Hard 2400 — 2600 $50

Submit your problem ideas using our Submission Form.

Happy problem proposing!

    Also the statement is unclear:
    - Statement section asks for leftmost digit, but input section asks for modulo 10 answer which is rightmost digit.
    - If we actually need rightmost digit then it's not enough to calculate answer modulo 10, we also should determine whether or not the answer is negative to actually get the rightmost digit.
