### Thanks goes to ASIS for organizing the CTF.
## Start
I downloaded the file from the description. It’s just a 7z file nested inside another 7z file with one file inside:
warmup
{see screenshot at URL above}

## Warmup
This is just a .c file with a bit of code put into a single line to read.
{see screenshot at URL above}

I tinkered with the code a bit, but I didn’t see anything wrong so I just tried to compile it. With enough effort I was able to get the correct GCC compile command with all the required imports. Here is the string I ended up with:
#### gcc warmup.c -o warmup.exe -include stdint.h -include stdio.h -include math.h

From there I just ran the exe and waited for a couple minutes.
