Hi @Zxey I liked, but it seems that the algorithm isn't properly implemented.

According to this the following gif:

From 1-100 the lucky numbers should be:

1, 3, 7, 9, 13, 15, 21, 25, 31, 33, 37, 43, 49, 51, 63, 67, 69, 73, 75, 79, 87, 93, 99

This is the link to your implementation repl.it/@abranhe/lucky-numbers-in-python online, I just set the range from 1 - 100.

In a part of the output you will see:

number 17 is not lucky
number 18 is not lucky
number 19 is lucky
number 20 is not lucky
number 21 is not lucky
number 22 is not lucky
number 23 is not lucky
number 24 is not lucky
number 25 is not lucky
number 26 is not lucky
number 27 is lucky
number 28 is not lucky

Where they don't match with the output it should be:

Eg:

• 19 isn't lucky
• 25 is lucky
• 27 isn't lucky
• and so on ...

So this need to be fixed to be merged, I am creating an issue right now, hopefuly we will implement correctly.

Fixed lucky numbers implementation as per AllAlgorithms/cpp#83 implementation.
