# 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
```Python3from 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()```Flag:> DawgCTF{jU$T_l1k3_w3lc0me_w33k}
