Codechef Long

How does the people do the points problem in the long contests and earn the whole point. What technique they use and how to learn that technique ?

They Basically Solve the Problem in an Efficient Way. They Write the code to Satisfy all the Test Cases.
The Points you get for solving the Partial marking Problem depends on the Range of Test Cases for which your code works.

You’ve been participating in the long contest since SEP’12 and now you are asking this question? And to get the 100 points your code has to pass all the test cases. It’s basically IOI format.

just consider the constraints…thats it…
