<section id="description"> Para un entero k positivo, defina d (k) como la suma de los dígitos de k en su representación decimal usual. Así d (42) = 4 + 2 = 6. <p> Para un entero positivo n, defina S (n) como el número de enteros positivos k <10n con las siguientes propiedades: k es divisible por 23 y d (k) = 23. </p><p> Se le da que S (9) = 263626 y S (42) = 6377168878570056. </p><p> Encuentra S (1112) y da tu respuesta mod 109. </p></section>
