Next

The package calculates asynchronously combinations and permutations of a collection of values.

To add the package recommended:

go get klaidliadon.dev/next

Functionalities

• Combinations
• Combinations with repetitions
• Permutations
• Permutations with repetitions

Usage

Just use create a new channel using Combination() or Permutation() and receive the results.

package main

import (
	"fmt"
	"klaidliadon.dev/next"
)

func main() {
	for v := range next.Combination([]interface{}{1,2,3,4}, 2, true) {
		fmt.Println(v)
	}
}

Produces

[1 1]
[1 2]
[1 3]
[1 4]
[2 2]
[2 3]
[2 4]
[3 3]
[3 4]
[4 4]

Roadmap

The 4 main cases of combinatronics are covered:

• Combinations
• Combinations with repetitions
• Permutations
• Permutations with repetitions

The future updates will improve performance and memory usage.
