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

Question

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 !!!

Answer 9

@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.

Answer 16

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?

Answer 17

@zephyr it's 10

Answer 19

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.
