this was my solution for the question 2-D Point Meeting (POINTMEE) it gave the correct answer on all subtasks except one!
I don’t know where my solution was lagging and what went wrong !
Please help me out with this

You could have asked this under official editorial of the problem as well (that way relevant discussions remain at one place), no need to create a new Discuss post !! 
I will take a look when i get time. In the meantime you can have a look at my C++ implementation - Solution: 51054146 | CodeChef
Go to the official editorial page. It has one such testcase.
I too had the same problem.
