5900f38e1000cf542c50fea1 | Problem 34: Digit factorials | 5 | 301998 | problem-34-digit-factorials |
--description--
145 is a curious number, as 1! + 4! + 5! = 1 + 24 + 120 = 145.
Find the numbers and the sum of the numbers which are equal to the sum of the factorial of their digits.
Note: as 1! = 1 and 2! = 2 are not sums they are not included.
--hints--
digitFactorial()
should return an object.
assert.typeOf(digitFactorial(), 'object');
digitFactorial()
should return { sum: 40730, numbers: [145, 40585] }.
assert.deepEqual(digitFactorial(), { sum: 40730, numbers: [145, 40585] });
--seed--
--seed-contents--
function digitFactorial() {
var sum = 0;
var numbers = [];
return { sum, numbers };
}
digitFactorial();
