stylus loop

A For loop and a while loop can be substituted for each other, such as:for (int i = 0; iUsing while to write isint i = 0;while (I...//INSERT statementi++;}The For loop is more concise and more common than the while, especially when using an array.But if you want to do an infinite loop, the while is more convenient, for

>>> A = [1,2,3,4,5,6]>>> for item in a: ... A.remove (item) ... >>> a[2, 4, 6]Does it feel strange to see the code above? Intuitively, we just want to remove each element of queue a sequentially, in turn, and why the final result is [2,4,6]? If you have enough wit, you should guess what the reason is. For each for loop, the current time a. After the Remove (item) execution is complete, a is relatively shortened, and the element following the i

The For loop and Forin loops are arrays and object iterations in the ES3, and the native Method Array.every () and Object.foreach () methods are added to the ES5 to iterate, and the following example is used to compare the speed of the two modes.Note: IE is not compatible./** * Created by Administrator on 2016/12/22. * for () loop and Array.every () method run speed */var arr=[5,6,12,23,0,11, "WASD", ' on '

Recently, when I wrote a shell script, I defined some variables in the while loop, but when I called them after exiting, we found that the variable values were empty, and it took a whole day to find the cause:I'm just doing a rough experiment here, explaining where the problem is, at the beginning of the code:#!/bin/shcat Config.ini | While read vardoa= $varecho $adoneecho "$a mark"[Email protected]_102 ~]# cat config.initest[[email protected]_102 ~]#

From JDK1.5, added a new feature foreach, which is a shorthand form for looping through data, using a keyword that is still for, but with a different parameter format. Its detailed usage is: for (Type e:collection) { Parameter description: E: Its type is the type of the element value in the collection or array, which is an element of the collection or array collection.Collections: A collection or array to traverse, or an iterator. The parameter e is used in the

This error occurs because some Linux systems use Ash to compile shell scripts by default, as is my machine, but the scripts I write should be executed with bash. Although I noted in the beginning #!/bin/bash, as if it is still the default to find Ash, it is very frustrating. Search the internet for a bit, find two solutions: 1, modify script 2, modify the system default execution Shell toolThe first kind of practice is that the original for loop is si
