# Two Truths and a Fib

The challenge gives us 3 numbers and we have to say which of these is from the fibonacci series.


I wrote this python script to solve the task

```Python3
from pwn import *

def controllo(n):
c=0
a=1
b=1
if n==0 or n==1:
print("Yes")
else:
while c<n:
c=a+b
b=a
a=c
if c==n:
return True
else:
return False

r = remote("umbccd.io", 6000)

for i in range(0,100):
r.recvuntil("[")
numeri = []
numeri = r.recvline().split()
numeri[0] = numeri[0][:-1]
numeri[1] = numeri[1][:-1]
numeri[2] = numeri[2][:-1]
for i in range(0,3):
if controllo(int(numeri[i])) == True:
r.sendline(bytes(numeri[i]))
else:
continue

r.interactive()
```
