裸的线段树还好，稍微一变就不会了，大佬说线段树是普及难度。。

线段树模板题都是普及➕/提高➖难度的好吗。模板线段树2还是提高➕/省选➖的呢，。

有意思，难度不是通过者自己选择的吗？

讲个笑话，要改这题难度，先把炒鸡玛丽和A+B改成入门---

@[XZZ\_\_233](/space/show?uid=23118) 超级玛丽至少TG。。眼睛都数瞎掉了。。。A+B你看看题解难道是入门题？？？
by MANCHERSTER @ 2017-09-23 23:54:38
@[MANCHERSTER](/space/show?uid=44617) 难道不是入门题？顶多树状数组线段树二分或者LCAfloyddijKStrabellmanfordspfa网络流费用流高精度读入优化输出优化或者是splayspalytreap什么的，乱搞就行
```pas
var a,b:int64;
begin
readln(a,b);
writeln(a+b);
end;
```
