**Description:**

Alors que vous êtes infiltré dans le repaire de **Hallebarde**, un des membres vous tend un jeu éléctronique qu'il a créé. Il vous met au défi de le battre. Il promet une belle récompense !\
`nc challenge.404ctf.fr 32697`

To solve this challenge, you need to exploit a flaw in the python script.\
In firsts trials, we try to send a numbre (50) then a word (test) to see the results of the program :\

We can see that any test are validated...\
After some search about flaw in python we can find that we can use `_` (underscore) between numbers, like this : `1_0_0_1`.\
And with trials and patience, we can find the flag when we send this : **`1_0_0_0_0_0_0_0_0_0_0_0_0_0_0_0_0_0_0_0_0_0_0_0_0_0`** :\
