Ok, let's port undocumented C code where I have no idea what it really
does to undocumented Python code where I have no idea what it really
does. It doesn't handle EOF by design, as input() is unsafe.

teste = 1
while 1:
    n = int(raw_input())
    if n == -1:
        break
    print "Teste %i\n%i\n\n" % (teste, ((1 << n)+1)*((1 << n)+1))
    teste += 1
