摘要： A Tour of Go系列。如有问题欢迎指出~这个也没什么好说的，就是试一下内建的复数运算。Let's explore Go's built-in support for complex numbers via thecomplex64andcomplex128types. For cube roots, Newton's method amounts to repeating:Find the cube root of 2, just to make sure the algorithm works. There is aPowfunction in themath 阅读全文

摘要： A Tour of Go系列。如有问题欢迎指出~closure即是俗话说的闭包，闭包三言两语说不清楚，而且本人也不甚了解。简单说就是语法定界，内部的函数可以引用外部上下文的变量，外部的变量会随之捕获并保存。一般来说带闭包的语言函数是可以作为first class的，Go也是如此。这意味这在Go中你可以以类似普通变量一样声明、赋值、传递一个函数变量。练习要求：Implement afibonaccifunction that returns a function (a closure) that returns successive fibonacci numbers.实现一个斐波那契数列函数， 阅读全文

摘要： A Tour of Go系列。如有问题欢迎指出~第三篇，先解释一下要求：ImplementPic. It should return a slice of lengthdy, each element of which is a slice ofdx8-bit unsigned integers. When you run the program, it will display your picture, interpreting the integers as grayscale (well, bluescale) values.The choice of image is up to y 阅读全文
