# GoGOLFplex
**Category:** Miscellaneous - **Points:** 990 - **Difficulty:** Easy - **Solves:** 111
**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`
**Solution:**
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`** :\
🚩 FLAG

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://writeups.ayweth20.com/2022/404ctf/misc/gogolfplex.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
