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 Ruby (2.3.3) (judge verdict: Accepted)

n, x, y = gets.split.map(&:to_i)

x -= 1
y -= 1

res = Array.new(n) { 0 }

(0...n).each do |i|
   ((i+1)...n).each do |j|
     d = 0
     if i <= x and y <= j
       d = (x - i) + 1 + (j - y)
     elsif i <= x and x < j
       d = (x - i) + [j - x, 1 + (y - j)].min
     elsif i < y and y <= j
       d = (j - y) + [y - i, 1 + (i - x)].min
     elsif x < i and j < y
       d = [j - i, (i - x) + 1 + (y - j)].min
     else
       d = j - i
     end
     
     res[d] += 1
   end
end

res[1...n].each do |x|
  puts x
