Factorial

Factorial

The factorial operation is encountered in many areas of mathematics, notably in combinatorics, algebra, and mathematical analysis. Its most basic use counts the possible distinct sequences – the permutations – of n distinct objects: there are n!.

Intro

import "github.com/digital-technology-agency/math"

func Example() {
    n := 4
    value := math.FactorialInt(n)
	fmt.Printf("Result: %d", value)
    /*
        Result: 24    
    */ 
}

Recalculate factorial with tree

import "github.com/digital-technology-agency/math"

func Example() {
    n := 4
    value := math.FactorialTreeString(n)
	fmt.Printf("Result: %s", value)
    /*
        Result: 24    
    */ 
}
