Implement WordCount. It should return a map of the counts of each “word” in the string s.

go_tour_ex3_map.go

package main

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

func WordCount(s string) map[string]int {
    m := make(map[string]int)
    words := strings.Fields(s)
    for _, w := range words {
        m[w] += 1
    }
    return m
}

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