## 思路分析

## 代码实现

```cpp
#include<bits/stdc++.h>

using namespace std;

#define endl '\n'

using ll = long long;

using ull = unsigned long long;

using PII = pair<int,int>;

using Pll = pair<ll,ll>;

int dx[4]= {-1,0,1,0},dy[4]= {0,1,0,-1};

const int inf = 0x3f3f3f3f;

int main() {

	ios::sync_with_stdio(0),cin.tie(0),cout.tie(0);

	int n,m;cin>>n>>m;

	ll sum=0;

	for(int i=0;i<m;i++){

		int jn;cin>>jn;

		sum+=jn;

	}

	ll ans=sum-(n*(m-1));

	cout<<max(0ll,ans);

	return 0;

}
```
