My implementation of WordCount in Go. Part of the Go tour: http://tour.golang.org/#40

WordCount.go

package main

import (
    "code.google.com/p/go-tour/wc"
    "strings"
)

func WordCount(s string) map[string]int {
    
    words := strings.Fields(s)
    wordCountMap := make(map[string]int)
    
    for _,word := range words{
        wordCountMap[word]++    
    }
    
    return wordCountMap
}

func main() {
    wc.Test(WordCount)
}

package main

import (
	"golang.org/x/tour/wc"
	"strings"
)

func WordCount(s string) map[string]int {
	wc := make(map[string]int)
	
	for _, word := range strings.Split(s, " ") {
		if _, exist := wc[word]; !exist {
			wc[word] = 0
		}
		
		wc[word] += 1
	}
	return wc
}

func main() {
	wc.Test(WordCount)
