package main

import "fmt"

func main() {
	var scores = 
	best := scores[0]

	for _, score := range scores {
		if score > best {
			best = score
		}
	}

	fmt.Println("scores=", scores)
	fmt.Println("best=", best)
}

package main

import "fmt"

func main() {
	var scores = 
	best := scores[0]

	for _, score := range scores {
		if score > best {
			best = score
		}
	}

	fmt.Println("scores=", scores)
	fmt.Println("best=", best)
}

package main

import "fmt"

func main() {
	var scores = 
	best := scores[0]

	for _, score := range scores {
		if score > best {
