*DAILY CHALLENGE* : Write a code that takes as input a number n, calculates the n'th "flyn number" and prints it to the screen.

INFO: 25 // 4 = 6 12 // 8 = 1 --> INTEGER DIVISION!!! TASK: The flyn-function is defined as following: f(x) = (x^3) // (x*3) = y (for x > 0) We call the number x a "flyn number" if the cros-sum of x and the cros-sum of y are equal. EXAMPLE: x = 27 y = (27^3) // (27*3) = 243 cros-sum(27) = cros-sum(243) = 9 ---> 27 is a "flyn number". GOOD LUCK AND HAVE FUN !!!

@Antoine "Why not >9..." (hang?) Line 2, your control variable is x (+1) Line 18, you modify x (back down) Based on how my JavaScript engine is hanging (my debug doesn't print and I can't run your code twice), it may be getting stuck in that loop.

@Antoine Bergerault In some langs (e.g. Python), // is integer division (divide and truncate).

I would like to get a clarification of the definition of cross sum. May I know what's the cross sum of 1234? Is it 10 or 1?

Hopefully not so behind on this one: https://code.sololearn.com/c662i46kCiZg If desired, this code could be easily modified to produce all flyn numbers up to and including the n-th one.
