RELOAD! There are 4852 unanswered questions (90.2588% answered)
@rolfl Why would you want that?
@rolfl Couldn't have described it better myself. Although my time counter is "only" 917 hours.
I want to feed speed modules in to beacons, but only turn them on when demanded.... otherwise beacons consume electricity for no output.
Trying to get dense beacons while using power cables with circuit-controlled power switch, is painful.
@rolfl Aaaah.... that'd be a really good feature-request.

Q: Sorting Algorithms in Go

treyhakansonI'm new to Go, so I implemented a few sorting algorithms for practice. For example, I have an in-place insertion sort, and a bubble sort: func bubbleSort(arr []int) { for i := 1; i < len(arr); i++ { if arr[i] < arr[i - 1] { tmp := arr[i - 1] arr[i - 1] = arr[i] ...

If you have working code that you think could be improved, see Code Review. If not, give a Minimal, Complete, and Verifiable example. Either way, code must be in the question on the SE network. — jonrsharpe 1 min ago

@Antoniossss yes I know stream.foreach does the same thing, for a straightforward situation it works very easily and I know it would also work and should work, but transforming this code looks a little bit difficult for me. I know it is a working code, but the code reviewer is asking to change the code. Regarding the exception those would be handled, those are also in pipeline. — hossaindoula 41 secs ago
