A simple function written in Go, to find the biggest integer in an integer slice using a recursive approach

rec_max_int.go

package main

import "fmt"

func max(arr []int) (m int) {

	if len(arr) > 2 {
		m = max( []int{ arr[0], max(arr[1:])} )
	} else {
		m = (map[bool]int{true : arr[0], false : arr[1]})[ arr[0] >= arr[1] ]
	}
	return
}

func main() {
	var s []int;
	s = make([]int, 10)
	s[0] = 1
	s[3] = 15
	s[9] = 8
    fmt.Println(max(s))
