Java发现缺少数字的问题 [英] Java finding a missing number problem

问题描述

大家好，

我需要解决一个关于java的问题。用户提供一个包含数字的字符串。缺少其中一个数字。第一个和最后一个数字可以介于-9999和9999之间，差异可以在-99到99之间。我的程序应该打印缺少的数字。

以下是一些例子：



510152030

25



567566565564563562561560559557556555554

558



828588919497100103106112115118121

109



-45-35-25-55152535455565
-15



我只掌握java的基本知识。（而且，for，if）

我不喜欢我想使用休息，继续，开关



我将非常感谢你的帮助...



< b>我尝试了什么：



我无法尝试任何东西，因为我的代码太长了。

Hello guys,
There is a problem about java i need to solve. The user provides a string which has numbers in it. One of the numbers is missing. The first and the last number can be between -9999 and 9999 and the difference can be between -99 and 99. My program should print the missing number.
Here are some examples:

-15

I only have a basic knowledge in java.( while,for,if)
I don't want to use break,continue,switch

I would appreciate your help...

What I have tried:

I could not try anything because my code gets too long.
