```cpp
#include<bits/stdc++.h>
using namespace std;
int main(){
double v=7,s,x,l=0;//v速度，s,x如题意
cin>>s>>x;
while(l<s-x){//游进探测器
l+=v;//路程累加
v*=0.98;//速度减慢
}
if(v*0.98<=s+x-l)cout<<'y';
else cout<<'n';
}
```

可以试试我的代码
```python
import random as r
a=r.randint(1,2)
if(a==1):
print("y")
else:
print("n")
```

不用特判吧，比大小就够了
