Here you can solve interesting problems using whatever programming language you like. Also you will earn SBI and sometimes STEM by doing so.
Also you might learn new things by doing so.
The tasks will be rather hard to solve without a programmable computer and some programming skills, but if you want to add a few million numbers by hand or similar, I would still give you the reward.

Imagine you have to write a program for a computer which is not able to multiply numbers and can only do addition, subtraction, comparison and bitwise operations. So you must write your own function to multiply integers.
Imagie further that this program needs to multiply numbers (that can get pretty big) very often, so that processing speed is crucial and the intuitive algorithm of simple repeated addition is not applicable.
Your task now is to write that function which multiplies two integers without using the "*" operator.

To everyone who already participated in a past contest, come back today and try a new problem(tell me if you don't want to be tagged):
In case no one gets a result(which I doubt), I will give away the prize to the person who makes the most constructive description why the problem is too hard in your opinion.
