之前自己一直在找自己感興趣的方向,以及在這個方向上流行的語言並嘗試學習這些語言其中的幾個但是沒有什麼重大發現,這篇文章主要介紹了15個出現在3個程式設計語言熱門排行榜的程式設計語言和他們的擅長的領域,他們分別是(排名不分先後):Python,Java,JavaScript,PHP,C#,C,C++,Ruby,Swift,Go/Golang,Scala,R,Objective-C,Perl。PythonPython is a general purpose programming

mac 安裝Golang 和 Liteide1、下載go下載地址:https://www.golangtc.com/downloadmac下載:go1.9.2.darwin-amd64.tar.gz,解壓到一個go目錄,把go目錄移動到你想要的路徑,我放在~/go 這個路徑下面。2、配置環境變數開啟終端,輸入命令 vim .bash_profile添加如下配置:#GOPATHexport GOPATH=~/Applications/Go#GOROOTexport
1.Fisher–Yates Shuffle(費雪耶茲 隨機置亂演算法) 演算法思想就是從原始數組中隨機抽取一個新的數字到新數組中。演算法英文描述如下:Write down the numbers from 1 through N.Pick a random number k between one and the number of unstruck numbers remaining (inclusive).Counting from the low end, strike out
在linux上想擷取檔案的元資訊,我們需要使用系統調用lstat或者stat。在golang的os包裡已經把stat封裝成了Stat函數,使用它比使用syscall要方便不少。這是os.Stat的原型:func Stat(name string) (FileInfo, error) Stat returns a FileInfo describing the named file. If there is an error, it will be of type
