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.

#include <stdio.h>
#include <math.h>
int main(void){
  int N;
  int i,x,y,z;
  scanf("%d",&N);
  for(i=1;i<=N;i++){

    for(x=1;x<=i/3;x++){
      
      for(y=1;y<=i/3;y++){
        
        for(z=1;z<=i/3;z++){
         
          if(pow(x+y+z,2)-x*y-y*z-z*x==i){
            s=s+1;
          }
        }
      }
    }
    printf("%d\n",s);
  }
  return 0;
