#include<bits/stdc++.h>
using namespace std;
int main()
{
int t;
cin>>t;
while(t--)
{
string s;
cin>>s;
int n=s.size();
vector<int>f(n+2),g(n+2);
for(int i=2,j=1;i<=n;i++)
{
if(s[i-1]!=s[j-1])j=i;
f[i]=f[j-1]+(i-j+1)/2;
}
for(int i=n-1,j=n;i;i--)
{
if(s[i-1]!=s[j-1])j=i;
g[i]=g[j+1]+(j-i+1)/2;
}
int l=1,r=n;
while(l<n&&s[l]==s[0])
l++;
while(r>1&&s[r-2]==s[n-1])
r--;
int res=f[n];
for(int i=1;i<n;i++)
{
int cur=f[i]+g[i+1];
if(s[0]==s[n-1])
{
int x=min(i,l),y=min(n-i,n-r+1);
if(x%2==1&&y%2==1)cur++;
}
res=min(res,cur);
}
cout<<res<<endl;
}
return 0;
}
这程序好像有点Bug,我给组数据试试?
