国旗如上：

str = '''– Look, I was gonna go easy on you not to hurt your feelings
– But I'm only to get this one chance
– Something's wrong, I can feel it (Six minutes, Slim Shady, you're on)
– Just a feeling, like something's about to happen, but I don't know what
It's a fatal mistake if you think I need to be overseas and take a vacation to tip a broad
And make a [?] on the face and don't be a retard
Be a king? Think not - why be a king when you can be a God?'''


new_str=str.split()
i=1
for c in new_str:
    if i < 5:
        print(c)
    elif i % 5 == 0:
        print("c
")
    else:
        print(c)
    i=i+1
