Problem 34: https://projecteuler.net/problem=34

145 is a curious number, as 1! + 4! + 5! = 1 + 24 + 120 = 145. Find the sum of all 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.

Module Contents

project_euler.problem_034.sol1.solution() → int

Returns the sum of all numbers whose sum of the factorials of all digits add up to the number itself. >>> solution() 40730

project_euler.problem_034.sol1.sum_of_digit_factorial(n: int) → int

Returns the sum of the factorial of digits in n >>> sum_of_digit_factorial(15) 121 >>> sum_of_digit_factorial(0) 1
