If a three digit ABC satisfies ABC = a ^ 3 + B ^ 3 + C ^ 3, such as 153 = 1 ^ 3 + 5 ^ 3 + 3 ^ 3, it is called "wonderful number", and the sum of all numbers satisfying the condition is obtained
This number is called "narcissus number". There are only four of the three numbers: 153370371407,
The sum of them is 1301
