```cpp
#include<bits/stdc++.h>
double x;
int main()
{
std::cin>>x;
std::cout<<ceil(log(1-x/100)/log(0.98));
return 0;
}
```

```
#include<stdio.h>
int main()
{float a,w,j;
int s=0;
scanf("%f",&w);
a=2;
do{
w-=a;
a*=0.98;
s++;
}while(w>0);
printf("%d",s);
return 0;
}
```

#include<bits/stdc++.h>
using namespace std;
long double x,sum=2,n=2,ans=1;
int main()
{
cin>>x;
for(int i=1;sum<x;i++)
{
sum=sum+sum/100*98;
n=sum;
ans++;
}
cout<<ans;
return 0;
}
为啥20分
