Problem Statement

Let f(n) be the number of triples of integers (x,y,z) that satisfy both of the following conditions:

1 \leq x,y,z

x^2 + y^2 + z^2 + xy + yz + zx = n

Given an integer N, find each of f(1),f(2),f(3),\ldots,f(N).

Constraints

All values in input are integers.

1 \leq N \leq 10^4

Input

Input is given from Standard Input in the following format:

N

Output

Print N lines. The i-th line should contain the value f(i).

For n=6, only (1,1,1) satisfies both of the conditions. Thus, f(6) = 1.

For n=11, three triples, (1,1,2), (1,2,1), and (2,1,1), satisfy both of the conditions. Thus, f(6) = 3.

For n=17, three triples, (1,2,2), (2,1,2), and (2,2,1), satisfy both of the conditions. Thus, f(17) = 3.

For n=18, three triples, (1,1,3), (1,3,1), and (3,1,1), satisfy both of the conditions. Thus, f(18) = 3.

Solution in C# (.NET Core 3.1.201) (judge verdict: Accepted)

using System;

class Program
{
    static void Main()
    {
        var N = int.Parse(Console.ReadLine());
        var sqrtN = (int)Math.Sqrt(N);

        var result = new int[N + 1];
        for (int i = 1; i <= sqrtN; i++)
        {
            for (int j = 1; j <= sqrtN; j++)
            {
                for (int k = 1; k <= sqrtN; k++)
                {
                    var v = i * i + j * j + k * k + i * j + j * k + k * i;
                    if (v <= N)
                    {
                        result[v]++;
                    }
                }
            }
        }
        for (int i = 1; i < result.Length; i++)
        {
            Console.WriteLine(result[i]);
        }
    }
}
