问题描述

我为数独写了代码

但是没有工作

}

我尝试过：



我创建了方法findlocationEmptyv

What I have tried:

I have created method findlocationEmptyv

推荐答案

因此，使用调试器确切地了解发生了什么：在函数的第一行放置一个断点，然后通过调试器运行代码。然后查看您的代码，并查看您的数据并找出手动应该发生的事情。然后单步执行每一行检查您预期发生的情况正是如此。如果不是，那就是当你遇到问题时，你可以回溯（或者再次运行并仔细观察）以找出原因。


抱歉，但我们不能为您做到这一点 - 时间让您学习一门新的（非常非常有用的）技能：调试！

So use the debugger to find out exactly what is happening: Put a breakpoint on the first line in the function, and run your code through the debugger. Then look at your code, and at your data and work out what should happen manually. Then single step each line checking that what you expected to happen is exactly what did. When it isn't, that's when you have a problem, and you can back-track (or run it again and look more closely) to find out why.

Sorry, but we can't do that for you - time for you to learn a new (and very, very useful) skill: debugging!
