Problem Statement

We have an undirected graph G with N vertices numbered 1 to N and N edges as follows:

For each i=1,2,...,N-1, there is an edge between Vertex i and Vertex i+1.

There is an edge between Vertex X and Vertex Y.

For each k=1,2,...,N-1, solve the problem below:

Find the number of pairs of integers (i,j) (1 \leq i < j \leq N) such that the shortest distance between Vertex i and Vertex j in G is k.

Constraints

3 \leq N \leq 2 \times 10^3

1 \leq X,Y \leq N

X+1 < Y

All values in input are integers.

Input

Input is given from Standard Input in the following format:

The graph in this input is as follows:

There are five pairs (i,j) (1 \leq i < j \leq N) such that the shortest distance between Vertex i and Vertex j is 1: (1,2)\,,(2,3)\,,(2,4)\,,(3,4)\,,(4,5).

There are four pairs (i,j) (1 \leq i < j \leq N) such that the shortest distance between Vertex i and Vertex j is 2: (1,3)\,,(1,4)\,,(2,5)\,,(3,5).

There is one pair (i,j) (1 \leq i < j \leq N) such that the shortest distance between Vertex i and Vertex j is 3: (1,5).

There are no pairs (i,j) (1 \leq i < j \leq N) such that the shortest distance between Vertex i and Vertex j is 4.

Solution in PyPy3 (2.4.0) (judge verdict: Accepted)

n, x, y = map(int, input().split())
a = [0 for i in range(n-1)]
for ii in range(n):
	for jj in range(ii+1,n):
		i = ii+1
		j = jj+1
		if i < x and j < x:
			b = j-i
		elif i < x and j >= x and j <= y:
			b = min(j-i, y-j+1+x-i)
		elif i < x and j > y:
			b = j-i-(y-x)+1
		elif i >= x and i <= y and j >= x and j <= y:
			b = min(j-i,i-x+y-j+1)
		elif i >= x and i <= y and j > y:
			b = min(j-i,i-x+1+j-y)
		else:
			b = j-i
		#print (i,j,b)
		a[b-1] += 1
for i in a:
	print (i)
