Description
Seja SB (n) o maior divisor de suavidade B de n. Exemplos: S1 (10) = 1 S4 (2100) = 12 S17 (2496144) = 5712
Defina F (n) = ∑1≤B≤n ∑0≤r≤n SB (C (n, r)). Aqui, C (n, r) indica o coeficiente binomial. Exemplos: F (11) = 3132 F (1 111) mod 1 000 000 993 = 706036312 F (111 111) mod 1 000 000 993 = 22156169
Encontre F (11 111 111) mod 1 000 000 993.
