Solve the ZCO and INOI previous year questions.

I see you have solved a lot of problems rated >=2200. But you are still in division-4. This might be some misfortune, or it could be something else. If you are copying the solution from others without understanding them, please don’t do that. At least try implementing the code by yourself after seeing other’s solutions.

For example, your solution for the problem Little Elephant and Painting is just a copy of the previous solution submitted by another user 2 months before you. Please don’t solve problems just for showing that you solve problems. Do it with dignity otherwise it won’t be of any use.
