@[Bilion_冰凌帅](/space/show?uid=54372) abs里面+1什麽鬼

@[羽儇](/space/show?uid=116162) 好像没什么问题啊XD
而且改成这样：
int abs(int x) {return x>=0?x:-x;}
还是WA啊XDD

令人眼花缭乱的双目运算符
记住，
a.size()>b.size()?~~b.push(a.top()),a.pop(~~):~~a.push(b.top()),b.pop()~~;
是错误的写法，用双目写时，不能加逗号
```cpp
#include<cstdio>
#include<queue>
using namespace std;
priority_queue<int,vector<int> > a;
priority_queue<int,vector<int>,greater<int> > b;
int abs(int x) {return x>=0?x:-x;}
int n,x,i;
int main()
{
scanf("%d %d",&n,&x); a.push(x); printf("%d\n",a.top());
for(i=2;i<=n;i++)
{
scanf("%d",&x);
x>a.top()?b.push(x):a.push(x);
while(abs(int(a.size())-int(b.size()))>1)
{
if(a.size()>b.size())b.push(a.top()),a.pop();
else a.push(b.top()),b.pop();
}
if(i%2) printf("%d\n",a.size()>b.size()?a.top():b.top());
}
return 0;
}
```
