import java.util.Scanner;

public class Test40031 {
public static void main(String []args ){
int ri, repeat,count, word,i;
String line;
char c;
Scanner in=new Scanner(System.in);
repeat=(in.nextLine()).charAt(0)-'0'; //输入repeat
for(ri=1; ri<=repeat; ri++){
line=in.nextLine(); //输入一行字符
/*---------*/
count=Count(line);
System.out.println(count);
}
}
public static int Count(String str){
String[] str1=str.split(" ");
int count=str1.length;
return count;
}
}追问谢谢你啊。。可是这道题貌似是程序填空题，所有的回答都要写在 /*---------*/里面，不能前后补充的。
