：TLE 是 Time Limit Exceeded 的缩写，即时间超限，表示你提交的程序运行使用了超出题目限定的时间

# 第一次提交

TLE！？😨这道几乎没什么逻辑的题怎么会超时呢？🤔

# 第二次提交

WTF！？说实话，当时我都觉得这道题就是来坑 Java 选手的 🙃

BufferedReader – (fast, but not recommended as it requires lot of typing): The Java.io.BufferedReader class reads text from a character-input stream, buffering characters so as to provide for the efficient reading of characters, arrays, and lines. With this method we will have to parse the value every time for desired type. Reading multiple words from single line adds to its complexity because of the use of Stringtokenizer and hence this is not recommended. This gets accepted with a running time of approx 0.89 s.but still as you can see it requires a lot of typing all together and therefore method 3 is recommended.

this method is very much recommended as it is easy to remember and is fast enough to meet the needs of most of the question in competitive coding.

🎉哇，可算通过了，不过就这么个问题 Java 用了这么长的代码，估计 C/C++ 要偷笑了
