Problem Statement
"NÄmec's quadratic law: how many minutes the teacher was late to the lesson, that many minutes squared he'll end the lesson earlier."
In other words, if the teacher is t minutes late (for some non-negative integer t), he should end the lesson t2 minutes early. Of course, this means the teacher can't be too late, because a lesson can't end before even starting. It is, however, possible for the teacher to arrive and end the lesson immediately (in fact, he then only arrives to tell the students that the lesson's cancelled).

Constraints
- d will be between 1 and 1,000,000,000,000,000,000, inclusive.
1 Returns: 0
The lesson was supposed to take 1 minute. The teacher can only be 0 minutes late, in which case he ends the lesson 0 minutes early (i.e. he arrives and ends the lecture on time).
2 Returns: 1
It's possible for the teacher to be 1 minute late and end the lecture 1 minute early (so there's no lecture at all).
5 Returns: 1
6 Returns: 2
7 Returns: 2
