CF755D.PolandBall and Polygon

PolandBall has such a convex polygon with $n$ veritces that no three of its diagonals intersect at the same point. PolandBall decided to improve it and draw some red segments.

He chose a number $k$ such that $gcd(n,k)=1$ . Vertices of the polygon are numbered from $1$ to $n$ in a clockwise way. PolandBall repeats the following process $n$ times, starting from the vertex $1$ :

Assume you've ended last operation in vertex $x$ (consider $x=1$ if it is the first operation). Draw a new segment from vertex $x$ to $k$ -th next vertex in clockwise direction. This is a vertex $x+k$ or $x+k-n$ depending on which of these is a valid index of polygon's vertex.

Your task is to calculate number of polygon's sections after each drawing. A section is a clear area inside the polygon bounded with drawn diagonals or the polygon's sides.

There are only two numbers in the input: $n$ and $k$ ( $5<=n<=10^{6}$ , $2<=k<=n-2$ , $gcd(n,k)=1$ ).

You should print $n$ values separated by spaces. The $i$ -th value should represent number of polygon's sections after drawing first $i$ lines.

The greatest common divisor (gcd) of two integers $a$ and $b$ is the largest positive integer that divides both $a$ and $b$ without a remainder.

For the first sample testcase, you should output "2 3 5 8 11". Pictures below correspond to situations after drawing lines.
