很简单的模拟
1 public static void main(String[] args) {
2 IO io = new IO();
3 String s=io.nextLine();
4 if (s.length()<3)io.println("No");
5 else {
6 int[]b=new int[200];
7 for (int i=2;i<s.length();i++){
8 b['.']=b['A']=b['B']=b['C']=0;
9 b[s.charAt(i-2)]=1;
10 b[s.charAt(i-1)]=1;
11 b[s.charAt(i)]=1;
12 if (b['A']+b['B']+b['C']==3){io.println("Yes");return;}
13 }
14 io.println("No");
15 }
16 }
