oh, good question, emmmm.......
lets suppose(just assumption

) that you are now a famous director of a tv drama
if you want to make the drama to be enough excellent, high ratings, what should you do
set a campy plot? nah~~~

lets come back to the code again, of course, we have to master them separately
and then making them fall in love again, so pls dont fail to them

, thats the way

DIR(s[j], s[j + 1]) ? (swap(s[j], s[j + 1])) : STUB;
(swap(s[j], s[j + 1])) 是gcc的表达式语句
这是gcc扩展
不是不能用
至少应该加个提示说明
讲清楚这是gcc扩展
