Goで再帰関数を作ってみる

package main

import (
	"fmt"
)

func fibonacci(n int) int {
	if n <= 1 {
		return n
	}
	return fibonacci(n-1) + fibonacci(n-2)
}

func main() {
	n := 10
	fmt.Printf("fibonacci(%d) = %d\n", n, fibonacci(n))
}

go run main.go

fibonacci(10) = 55

package main

import (
	"fmt"
)

func factorial(n int) int {
    if n <= 1 {
        return 1
    }
    return n * factorial(n-1)
}

func main() {
	n := 10
	fmt.Printf("factorial(%d) = %d\n", n, factorial(n))
}

go run main.go

factorial(5) = 120
