两种分支模式，猜错几次

运行下面这段程序，填写它打印出来的结果。

STAGES = 5
FLUSH = 3

def pipelined(n):
    return n + STAGES - 1

def wrong_guesses(pattern):
    last = -1
    wrong = 0
    for t in pattern:
        if last == -1 or t != last:
            wrong = wrong + 1
        last = t
    return wrong

REG = [1] * 16
ALT = [1, 0] * 8
print(str(wrong_guesses(REG)) + "/" + str(wrong_guesses(ALT)))
