We have another of those easy to state but hard to do puzzles this week.
There are four three-digit numbers that equal the sum of the cubes of their digits, and your challenge is to find them.
For example, with 123, 1 cubed + 2 cubed +3 cubed = 1 + 8 + 27 = 36, which doesn't work. But there are four numbers that do work - can you find them?
