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:

N X Y

Output

For each k=1, 2, ..., N-1 in this order, print a line containing the answer to the problem.

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 Python (3.4.3) (judge verdict: Wrong Answer)

N, X, Y = [int(n) for n in input().split()]
C = (X + Y + 1) / 2

ans = [0] * (N - 1)
for i in range(1,N):
    for j in range(i+1,N+1):
        if i <= X:
            if j <= C:
                k = j - i
            elif j < Y:
                k = X - i + 1 + Y - j
            else:
                k = X - i + 1 + j - Y
        elif i <= Y:
            if j < Y:
                if j <= i + C:
                    k = j - i
                else:
                    k = i - X + 1 + Y - j
            else:
                if i <= (X + Y - 1) / 2:
                    k = i - X + 1 + j - Y
                else:
                    k = j - i
        else:
            k = j - i
        ans[k-1] += 1

print("\n".join([str(n) for n in ans]))
