word_count.go

import (
  "fmt"
  "strings"
)

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

func main() {
  result := WordCount("Hello there, how are you doing today? I hope you are doing well.")
  fmt.Println(result)   // output: map[Hello:1 how:1 you:2 well.:1 there,:1 are:2 doing:2 today?:1 I:1 hope:1]
}
