真麻烦！
代码给你看看：
```c
#include<iostream>
#include<cstdio>
#include<algorithm>
#include<cmath>
#include<string>
#include<cstring>
#include<cstdlib>
using namespace std;
int a[10005];
int main(){
int N,ave=0,ans=0;
cin>>N;
for(int i=0;i<N;++i){
cin>>a[i];
ave+=a[i];
}
ave/=N;
for(int i=0;i<N;++i){
a[i]-=ave;
}
for(int i=0;i<N;++i){
if(a[i]!=0){
a[i+1]+=a[i];
ans++;
}
}
cout<<ans;
return 0;
}
```
