Por exemplo:
f (4) = 411728896 (4411728896 = ... 490411728896) f (10) = 0 f (157) = 743757 (157743757 = ... 567000743757) Σf (n), 2 ≤ n ≤ 103 = 442530011399 Localizar Σf (n ), 2 ≤ n ≤ 106.
euler455()
deve retornar 450186511399999.
testString: 'assert.strictEqual(euler455(), 450186511399999, "euler455()
should return 450186511399999.");'
