A Tour of Go. Exercise: Maps. Implement WordCount. It should return a map of the counts of each “word” in the string s. The wc.Test function runs a test suite against the provided function and prints success or failure. You might find strings.Fields helpful.

exercise-41.go

package main

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

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

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

Where can i get wc package?

Leaving this here just for reference.
