    Java 15:

    import java.io.*;
import java.util.*;
import java.util.regex.Pattern;
import java.util.regex.Matcher;
public class Solution {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        // Pattern pattern = Pattern.compile("(ok){3,}");   //WORKS
        Pattern pattern = Pattern.compile("(ok)\\1\\1");    
        // \\1 means anything in first captured-group. Here ok is in first ()
        Matcher matcher = pattern.matcher(scanner.nextLine());
        System.out.println(matcher.find()); 
    }
}
