Gocap

Calculate permutations and combinations in go

Installation

With a correctly configured Go toolchain:

go get -u github.com/jaumecapdevila/gocap

Usage

First of all you need to create a new instance of the Operation struct using the NewOperation constructor:

operation := NewOperation(3, 1, false)

This constructor receives three parameters:

1. N: the number of different types
2. R: the number of types to choose
3. Repetition: Indicates if its possible or not to repeat a type

Now, you can use the CombinationCalculator and the PermutationCalculator to get the result of the operation:

calculator := NewCombinationCalculator()

result := calculator.Calculate(operation)
