#include<bits/stdc++.h>
using namespace std;
const int N=1e6+5;
char s[N];
int n,ans,cnt;
int main(){
scanf("%s",s+1);
n=strlen(s+1);
int len=0;
s[n+1]='0';
for(int i=1;i<=n+1;++i){
if(s[i]=='0'){
if(len){
ans+=(len-1)/2;
if(len&1)ans++;
else cnt++;
}
len=0;
}
else len++;
}
printf("%.10lf",ans+sqrt(2)*cnt);
}
这程序好像有点Bug，我给组数据试试？
