@[charm1](/space/show?uid=135258) 可不可以看一下我的代码哪里有错误呢？

你这个码风跟我不一样，，看不了

@[仗剑走天涯_ZHX](/space/show?uid=223290) 我直接模拟……………………

别在主函数定义数组

@[仗剑走天涯_ZHX](/space/show?uid=223290) 我的代码太复杂了，不如各位大佬的简介。我是初学者，emm……唉，太难了

不然洛谷会炸
by charm1 @ 2019-10-04 22:42:25
@[charm1](/space/show?uid=135258) 把数组定义到主函数以外，还是一样的结果两个WA一个RE

@[JryACtrying](/space/show?uid=52067) 定义全局变量
by charm1 @ 2019-10-04 22:46:58
@[charm1](/space/show?uid=135258)
```cpp
#include<iostream>
#include<algorithm>
using namespace std;
const int MAX=5100;
struct tt{
int xi;//hight
int yi;//strength
};
tt tao[MAX];
tt nw[MAX];
bool comparisonxi(tt a,tt b){
return a.xi<b.xi;
}
bool comparisonyi(tt a,tt b){
return a.yi<b.yi;
}
int main()
{
int n,a,s,xi,yi,b;
int i;
int num=0,temp=0;
int k;
cin>>n>>s>>a>>b;
//scanf("%d%d%d%d",&n,&s,&a,&b);
for(i=1;i<n;i++)
{
cin>>tao[i].xi>>tao[i].yi;
// scanf("%d%d",&xi,&yi);
}
sort(tao+1,tao+n,comparisonxi);
for(i=1;i<=n;i++)
{
if(tao[i].xi<=(a+b))
{
nw[i].xi=tao[i].xi;
nw[i].yi=tao[i].yi;
num++;
}
else break;
}
sort(nw+1,nw+num+1,comparisonyi);
k=num;
for(i=1;i<=num;i++)
{
if(b>=0&&k>0)
{
b=b-nw[i].yi;
temp++;
k--;
}
else break;
}
cout<<temp;
return 0;
}
```
改成了全局变量还是一样的结果，我哭了……
