1. If you use "." As a separate word, it must be written as follows: String.Split ("\ \"), in order to properly separate, can not be used String.Split (".");2. If you use "|" As a separate word, it must be written as follows: String.Split ("\\|"), so as to properly separate, can not be used String.Split ("|");Reason:"." and "|" is an escape character and must be added "\ \";3.

Scale out (also scale horizontally) scales horizontally, scaling outScale up (that is, scale vertically) scales vertically, scaling upScale Out,scale Up,scale in is actually a concept of architecture that can be used on storage, on a database, and on a network.The simple analogy of scale out and scale up helps us understand:Scale out, for example: We add a new machine to the original web and mail system.Scale up, for example: We add CPU, memory to the original machine.Horizontal

Given an array with n integers, you need to find if there is triplets (I, J, K) which satisfies following conditions: 0 Sum of Subarrays (0, i-1), (i + 1, j-1), (j + 1, k-1) and (k + 1, n-1) should be equal. Where we define that Subarray (L, R) represents a slice of the original array starting from the element indexed L to the E Lement indexed R.Example:Input: [1,2,1,2,1,2,1] Output: TrueExplanation:i = 1, j = 3, k = 5. SUM (0, i-1) = SUM (0, 0) = 1sum (i + 1, j-1) = SUM (2, 2

Often we want to use the bulk operation will be used to split the string, the sad is that SQL Server does not have a split function, so we can only do it ourselves to solve. In order to reduce the number of communications with the database, we will use this method to achieve bulk operations. Of course, sometimes we use the Execute method to implement this, one of the bad things about using this method is th

It's OK to do something like this: 1. Open a worksheet with Excel2013, select the location where we need to split the panes, switch to the View tab, and click the Split button in the window. 2.

The title of the article starts with a bit of a detour, such as executing a command pipeline. Haha, due to server settings problems, you cannot upload a large compressed package. This compressed package cannot be resumed, and all of it can only be cut, if you use software in windows, you can easily solve the problem. In Linux, you only need two commands:First, let's look at the first command:Cat jordan_shoes.tar.gz | split-B 100 m-jordan_shoes.tar.gz.
