package main

import (
	"golang.org/x/tour/wc"
	"strings"

// 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.
func WordCount(s string) map[string]int {
    i := strings.Split(s, " ")
	// i := strings.Fields(s) // This also works and splits a string on surrounding whitespace
	m := make(map[string]int)
	for j := 0; j < len(i); j++ {
	  m[i[j]]++
	}
	return m
}
