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++ (GCC 9.2.1) (judge verdict: Wrong Answer)

#include <bits/stdc++.h>
using namespace std;
#define ll long long

const int MAXN = 1e4;
int a[MAXN+1];

int main() {
	int n;
	cin >> n;
	ll sum = 0;
	for(int i=1; i<=n; i++) {
		for(int j=1; j<=n; j++) {
			for(int k=1; k<=n; k++) {
				sum = (i*i)+(j*j)+(k*k)+(i*j)+(j*k)+(i*k);
				if(sum <= MAXN) {
					a[sum] ++;
				}
			}
		}
	}
	for(int i=0; i<=n; i++) {
		cout << a[i] << "\n";
	}
	return 0;
