## Description
```
We are given an IP address and a port to connect to, upon connecting we are asked to solved the following equation:
X > 1337
X * 7 + 4 = 1337
```
## Solution
It is pretty obvious that we to do an integer overflow, after some manual testing I used the following dirty C code:
```
#include <stdio.h>
#include <stdlib.h>
int main(int argc, char **argv) {
int x = 610000000;
int i = 0;
for (i; i<100000000; i++) {
if ((x+i)*7 + 4 == 1337) printf("%d", i);
}
}
```
which gives us the answer: 613566947
## Results
```
Solve the following equations:
X > 1337
X * 7 + 4 = 1337
Enter the solution X: 613566947
You entered: 613566947
613566947 is bigger than 1337
1337 is equal to 1337
Well done!
