what if I have only problem but not able to develop its problem can I still submit my idea?? PS:- I don't know anything about problem setting
Problem-setting includes : making the statement, making the working solution, making the test data and also making the checker program if interactive/multiple valid answers. You get feedback from coordinator/admin and also from testers.
After all this, when you problem has been successfully used in a contest without any issues, you are eligible to get the money.
Yes.
How to do total overlap?
Divide the number line into disjoint intervals, count the number of segments in both $$$A$$$ and $$$B$$$ containing each interval using difference arrays and then add contribution of each interval separately.
The editorial is ready, would be out by morning.
