Generic Combinations and Permutations

Although I don't anticipate using it much, I decided to give go generics a try. I've been known to toss the old void pointer around in C on occasion.

Overview

Package combs provides generic functions for producing combinations and permutations from slices of any type.

Index

• func Combinations[T any](n int, v []T) <-chan []T
• func Permutations[T any](a []T) <-chan []T

Functions

func Combinations

func Combinations[T any](n int, v []T) <-chan []T

Creates a channel that returns all combinations of n items from the slice v.

func Permutations

func Permutations[T any](a []T) <-chan []T

Creates a channel that returns all permutations of a slice of any type. Uses Heap's Algorithm (thanks wikipedia)
