#include<bits/stdc++.h>
#define int long long
#define  For(i,a,b) for(ll i=(a);i<=(b);i++)
using namespace std;
typedef long long ll;

string s;
ll n,ans;
signed main()
{
    ios::sync_with_stdio(false);
    ll T;
    cin>>T;
    while(T--){
        cin>>s;
        n=s.size();
        ll now=0,fst=0;
        ans=0;
        For(i,1,n){
            if(i==1){
                if(s[i-1]=='1') fst++;
                if(s[i-1]=='0') fst+=2;
            }
            if(i!=1){
                if(s[i-1]==s[i-2]) fst+=2;
                if(s[i-1]!=s[i-2]) fst++;
            }
            now+=fst;
        }
        ans+=now;
        For(i,1,n-1){
            now-=(n-i+1);
            if(s[i-1]=='0') now-=(n-i+1);
            if(s[i]==s[i-1]) now-=(n-i);
            if(s[i]=='0') now+=(n-i);
            ans+=now;
        }
        cout<<ans<<'\n';
    }

    return 0;
}

这程序好像有点Bug,我给组数据试试?
