Solve script:

```python
import pwn

p = pwn.remote("167.71.143.44", "31273")
p.sendline("1")
for i in range(100):
print(i)
p.recv()
p.sendline("rockpaperscissors")
p.interactive()
```

The challenge server only checked for the existence of the solution in our input string, so we could pass all three solutions at once.
