If your variable and function names don't explain what is going on, you will encounter a big maintenance problem with your code as non-updated comments contradict your unreadable code. Very occasionally I find a use for attention-grabbing comments, number one for this, and personally I

Re: [go-nuts] Go-path from a source other than $GOPATH (and package management)

You are right. That is very similar except that, instead of having a convention for naming directories, there should exist a .goenv in the working directory (or a up parent). In this .goenv file a go-path can be set - and maybe other go env vars. This way, it is possible to take advantage of

You need to show the input file also. I can only guess this has something to do with maybe cr/lf? What happens if you add a distinct separator to the input such as a semicolon? On Thursday, 19 April 2018 20:31:56 UTC+3, Alex Dvoretskiy wrote: > > Hello Golang-nuts, > > Following code reads data

Hello Golang-nuts, Following code reads data from file and creates binary tree structure: ' // go run main.go < input package main import "fmt" type TreeNode struct { Value int Left *TreeNode Right *TreeNode } func main () { nodes := read() for i, node := range(nodes) { fmt.Printf("%p\n",

Yes, to use the functions above you will need to copy the slices of landSpaceto slices of the respective interface types. But I you do not need to do any type assertions. Like this: https://play.golang.org/p/eFTUqpImyPc package main import ( "fmt" ) type landSpace struct{} func

Re: [go-nuts] Re: Why not tuples?

Multiple return values. They do kinda exist in a declarative form of sorts, in the type signature, this sets the number and sequence and types of return values. You could even make functions accept them as also input values, I think, but I don't think it works exactly like this. I'm not a fan

Re: [go-nuts] Extension for type assertion of interface array

Though the above is not allowed, you can restructure your code to wrap your struct as array in another struct and have area() paas a index to the underlying struct. Something like this (landSpaceArr wraps landSpace struct) - type landSpace struct{ side int } type landSpaceArr struct

[go-nuts] Re: parallel array processing question

When you have such questions, then run your code with the race detector. https://golang.org/doc/articles/race_detector.html Otherwise, you are only reading from the slice, there is no racing possible. Also, your max function looks very weird and has a small bug:

Re: [go-nuts] Re: Why not tuples?

Just to clarify. Yes, the parent/child relationships are purely based on the indices of the nodes. It's not a conventional vector reference based binary tree. I was surprised when I came up with the idea that such did not even exist. Just to explain, it's a non-rectilinear array mapping. There
