Introduction Log files are files that contain messages about the system, including the kernel, services, and applications running on it. There are different log files for different information. For example, there is a default system log file, a log f…

Given a non-empty string, encode the string such that its encoded length is the shortest. The encoding rule is: k[encoded_string], where the encoded_string inside the square brackets is being repeated exactly k times. Note: k will be a positive integ…

Given an encoded string, return it's decoded string. The encoding rule is: k[encoded_string], where the encoded_string inside the square brackets is being repeated exactly k times. Note that k is guaranteed to be a positive integer. You may assume th…

一次又一次的,我发现,那些有bug的Javascript代码是由于没有真正理解Javascript函数是如何工作而导致的(顺便说一下,许多那样的代码是我写的).JavaScript拥有函数式编程的特性, 当我们选择面对它的时候,这将成为我们前进的阻碍. 作为初学者,我们来测试五种函数调用的方法,从表面来看我们会认为那些函数与C#中函数的作用非常相似,但是我们一会儿可以看到还是有非常重要的不同的地方的,忽视这些差异无疑会导致难于跟踪的bug.首先让我们创建一个简单的函数,这个函数将在将在下文中使用…
