Good morning everyone.

I wanted to do something other than cp these days since IOI selection is coming soon.So i decided to make something like an checker to find coupons.

To be more detailed there is a popular site in my country where you order food online.However there is a coupon place were you put a coupon number/string an you get some money off.

So the guy who made the site is not good and he made it such that the coupons are always of the form foodlove and some number after.

Like a coupon might be foodlove133 ,foodlove4556 .So its foodlove and a number with at most 10 digits.

But not all coupons are valid.

So i want to find someone with experience before to help me make a program that automatically checks every coupon and finds all that are valid. You will be rewarded good to help me to this.

Also this has nothing to do with cp, its more on the practical side rather than the algorithms side.

Dm me to know more and to help me.

Thank you!
