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.

Instructions

Tests

tests:
  - text: '<code>digitFactorial()</code> should return { sum: 40730, numbers: [145, 40585] }.'
    testString: "assert.deepEqual(digitFactorial(), { sum: 40730, numbers: [145, 40585] });"

Challenge Seed

function digitFactorial() {
  // Good luck!
  var sum = 0;
  var numbers = [];
  return { sum, numbers };
}

digitFactorial();
