func wordCount(s string) map[string]int {
    words := strings.Fields(s)
    counts := make(map[string]int)
    for _, word := range words {
        _, exist := counts[word]
        if exist {
            counts[word] += 1
        } else {
            counts[word] = 1
        }
    }
    return counts
}
 
func main() {
    s := "go java c++ go c++ go php php python"   
    for word, count := range wordCount(s) {
        fmt.Println(word, "=", count)
