早合并和晚合并，冲突差多少

同样两条分支，如果分支只做了第一步就合回来（只改了 HOST），和拖到现在才合，冲突数各是多少？运行下面这段程序：

def classify(b, o, t):
    if o == t:
        return "same"
    if o == b:
        return "theirs"
    if t == b:
        return "ours"
    return "conflict"

def kinds(base, ours, theirs):
    return [classify(b, o, t)
            for b, o, t in zip(base, ours, theirs)]

base = ['HOST = "localhost"', 'PORT = 8000', 'DEBUG = False',
        'TIMEOUT = 30', 'RETRY = 1', 'LOG = "app.log"']
ours = ['HOST = "localhost"', 'PORT = 8080', 'DEBUG = True',
        'TIMEOUT = 60', 'RETRY = 1', 'LOG = "main.log"']
theirs = ['HOST = "0.0.0.0"', 'PORT = 9000', 'DEBUG = True',
          'TIMEOUT = 30', 'RETRY = 3', 'LOG = "sys.log"']
early = ['HOST = "0.0.0.0"', 'PORT = 8000', 'DEBUG = False',
         'TIMEOUT = 30', 'RETRY = 1', 'LOG = "app.log"']
print(str(kinds(base, ours, early).count("conflict")) + "/" +
      str(kinds(base, ours, theirs).count("conflict")))
