代码哪错了？？```cpp
#include<bits/stdc++.h>
using namespace std;
int main(){
int i=1,j,k,x,n=0,maxx,m=0,a[10000],b[10000],h[10000];
int z;
cin>>z;
memset(a,0,sizeof(a));
memset(b,0,sizeof(a));
memset(h,0,sizeof(a));
while(cin>>a[i]){
maxx=0;
for(j=1;j<=i-1;j++){
if(a[j]>=a[i]){
if(b[j]>maxx){
maxx=b[j];
}
}
}
b[i]=maxx+1;
if(b[i]>m){
m=b[i];
}
x=0;
for(k=1;k<=n;k++){
if(h[k]>=a[i]){
if(x==0){
x=k;
}else if(h[k]<h[x]){
x=k;
}
}
}
if(x==0){
n++;
x=n;
}
h[x]=a[i];
i++;
}
cout<<m<<endl;
cout<<n<<endl;
return 0;
}
