A Tour of Go Exercise:Maps i 44

Go 语言练习 A Tour of Go

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 (
    "tour/wc"
    "strings"
)

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

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