import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.Random;

public class Guess {
    public static Random r = new Random();
    public static BufferedReader in = new BufferedReader(
            new InputStreamReader(System.in));

    public static final String YES_S = "y";

推荐答案

好吧，让我们分解一下for循环:

Well, let's decompose your for loop:

for (int i = 0; i > 3; i++) 

1. 以i = 0
开头
2. 在i > 3的同时做身体....哎呀，你看到问题了吗?

1. Start with i = 0
2. Perform the body while i > 3 .... whops, do you see the problem?
