| ## Description
 | ||
| <section id="description"> Considere el conjunto S (r) de puntos (x, y) con coordenadas enteras que satisfacen | x | + | y | ≤ r. Sea O el punto (0,0) y C el punto (r / 4, r / 4). Sea N (r) el número de puntos B en S (r), de modo que el triángulo OBC tenga un ángulo obtuso, es decir, el ángulo mayor α satisface 90 ° <α <180 °. Entonces, por ejemplo, N (4) = 24 y N (8) = 100. <p> ¿Qué es N (1,000,000,000)? </p></section>
