```cpp
#include<bits/stdc++.h>
using namespace std;
int n,x;
int main(){
long long s=0;//要长
cin>>n>>x;
int a[n];
cin>>a[1];
if(a[1]>x){//跳过1，从中间开始可最少
s+=a[1]-x;
a[1]=x;
}for(int i=2;i<=n;i++){
cin>>a[i];
if(a[i]+a[i-1]>x){//判定时间~~
s+=a[i]+a[i-1]-x;
a[i]=x-a[i-1];
}
}cout<<s<<endl;
return 0;
}

### 加一个long long 就好了
帮你改了一下:
```
#include<bits/stdc++.h>
using namespace std;
long long x,n,ans=0,a[100005];
int main(){
cin>>n>>x;
for(long long i=1;i<=n;i++){
cin>>a[i];
}
for(long long i=1;i<=n;i++){
while(a[i]>x){
a[i]--;
ans++;
}
while(a[i]+a[i+1]>x){
a[i+1]--;
ans++;
}
}
cout<<ans<<endl;
return 0;
}
```
