Integer Sequence Dividing
Integer Sequence Dividing
You are given an integer sequence 1, 2, ..., n. You have to divide it into two sets A and B in such a way that each element belongs to exactly one set and |sum(A) - sum(B)| is minimum possible.
The value |x| is the absolute value of x and sum(S) is the sum of elements of the set S.
Input
The first line of the input contains one integer n (1 ≤ n ≤ 2 ⋅ 10^9).
Output
Print one integer — the minimum possible value of |sum(A) - sum(B)| if you divide the initial sequence 1, 2, ..., n into two sets A and B.
Examples
Input
3
Output
0

Input
6
Output
1
Note
Some (not all) possible answers to examples:
In the first example you can divide the initial sequence into sets A = {1, 2} and B = {3} so the answer is 0.
In the second example you can divide the initial sequence into sets A = {1, 3, 4} and B = {2, 5} so the answer is 1.
In the third example you can divide the initial sequence into sets A = {1, 4, 5} and B = {2, 3, 6} so the answer is 1.
