```cpp
#include<bits/stdc++.h>
using namespace std;
int a[10001];
int main() {
int n,i,j,k,l=0,b=0,t;
cin>>n;
for(i=1;i<=n;i++) cin>>a[i];
for(i=1;i<=n-1;i++)
{
for(j=i+1;j<=n;j++)
{
b++;
if(a[i]>=a[j])
t=a[i]-a[j];
else t=a[j]-a[i];
for(k=1;k<=n;k++)
{
if(t==k) l++;
}
}
}
if(l==b) cout<<"Jolly"<<endl;
else cout<<"Not jolly"<<endl; return 0;
}

题目中说的是绝对值
by zybnxy @ 2018-10-05 20:06:48
```cpp
#include<cstdio>
#include<algorithm>
using namespace std;
int a[1001],f[1001];
int abs(int v){return v>0?v:-v;}
int main()
{
int n,i;
scanf("%d",&n);
for(i=1;i<=n;i++)scanf("%d",&a[i]);
for(i=1;i<n;i++)f[i]=abs(a[i]-a[i+1]);
sort(f+1,f+n);
for(i=1;i<n;i++)
if(f[i]!=i){printf("Not jolly\n");return 0;}
printf("Jolly\n");
return 0;
}
```
这样写多好，又简洁
