AC10个点，其余均TLE 代码：

#include <iostream>
#include<iostream>
using namespace std;
int i,j,k,x,n,maxx,m,a[1000000],b[1000000],h[1000000];
int main()
{
    i=1;n=0;m=0;
    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<<n;
    return 0;
}

求代码！！！！！！！！！
