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] = 1
}else{
m[value] = v + 1
}
}
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 := 0; i < len(strs); i++ {
v, ok := m[strs[i]]
if !ok {
m[strs[i]] = 1
}else{
m[strs[i]] = v + 1
}
}
return m
}

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