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.

package main

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

func WordCount(s string) map[string]int {
    m := make(map[string]int)
    strs := strings.Fields(s)
    for _,value := range strs {
        v, ok := m[value]
        if !ok {
            m[value] =
        }else{
            m[value] = v +
        }
    }
    return m
}

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

package main

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

func WordCount(s string) map[string]int {
    m := make(map[string]int)
    strs := strings.Fields(s)
    for i := ; i < len(strs); i++ {
        v, ok := m[strs[i]]
        if !ok {
            m[strs[i]] =
        }else{
            m[strs[i]] = v +
        }
    }
    return m
}

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