Exercise: Map

Implement ' WordCount '. It should return a map containing the s number of "words" in each. wc.TestThe function executes a test case against the function and prints the success or failure.

You'll find strings. fields are very helpful.

My Code:

Package Mainimport (    "CODE.GOOGLE.COM/P/GO-TOUR/WC"    "Strings"    ) func WordCount (s string) Map[string]int {     str: = strings. Fields (s)//divide the string into the word array  m: = Make (Map[string]int) for  I:=0;i<len (str); I++{if m[str[i]]==0{  m[str[i]]= 1}else{  m[str[i]]++}  }return M}func main () {WC. Test (WordCount)}

Operation Result:

PASS F ("I am learning go!") =   map[string]int{"I": 1, "AM": 1, "Learning": 1, "go!" : 1}pass F ("The quick brown fox jumped over the lazy dog.") =   map[string]int{"Quick": 1, "Fox": 1, "jumped": 1, "the": 1, " The ": 1," Over ": 1," lazy ": 1," dog. " : 1, "Brown": 1}pass f ("I ate a donut. Then I ate another donut. ") =   map[string]int{"ate": 2, "a": 1, "Donut." : 2, "then": 1, "another": 1, "I": 2}pass F ("A mans a plan A canal Panama.") =   map[string]int{"A": 1, "Man": 1, "A": 2, "plan" : 1, "Canal": 1, "Panama." : 1}
