這篇文章主要介紹了go語言如何統計英語文章的單詞數量,具有一定借鑒價值,感興趣的朋友可以參考下,希望大家閱讀完這篇文章之后大有收獲,下面讓小編帶著大家一起了解一下。
package main
import ( "fmt" "sort" ) func wordCounterV1(str string) { /*定義變量*/ stringSlice := str[:] temp := str[:] wordStatistic := make(map[string]int) /*把所有出現的單詞放入map中*/ j := 0 for i := 0; i < len(stringSlice); i++ { if !((stringSlice[i] >= 65 && stringSlice[i] <= 90) || (stringSlice[i] >= 97 && stringSlice[i] <= 122)) { temp = str[j:i] if len(temp) != 0 { wordStatistic[temp]++ } j = i + 1 } } /*把首字母為大寫的單詞轉換為小寫;去除無效字符*/ for i := range wordStatistic { if len(i) > 1 { if (i[0] >= 65 && i[0] <= 90) && (i[1] <= 65 || i[1] >= 90) { strTemp := make([]byte, len(i), len(i)) copy(strTemp, i) strTemp[0] += 32 wordStatistic[string(strTemp)] += wordStatistic[i] delete(wordStatistic, i) } } else { if i[0] != 'a' && i[0] != 'A' { delete(wordStatistic, i) } else if i[0] == 'A' { wordStatistic["a"] += wordStatistic[i] delete(wordStatistic, i) } } } /*把map的關鍵字映射到string切片進行排序*/ sortSlice := make([]string, 0, len(wordStatistic)) for i := range wordStatistic { sortSlice = append(sortSlice, i) } sort.Strings(sortSlice) /*輸出結果*/ for _, v := range sortSlice { fmt.Printf("%s:%d\n", v, wordStatistic[v]) } fmt.Printf("word count:%d\n", len(wordStatistic)) }
主函數隨便輸入一篇英語文章
func main() { str := ` There are moments in life when you miss someone so much that you just want to pick them from your dreams and hug them for real! Dream what you want to dream;go where you want to go;be what you want to be,because you have only one life and one chance to do all the things you want to do. May you have enough happiness to make you sweet,enough trials to make you strong,enough sorrow to keep you human,enough hope to make you happy? Always put yourself in others'shoes.If you feel that it hurts you,it probably hurts the other person, too. The happiest of people don't necessarily have the best of everything;they just make the most of everything that comes along their way.Happiness lies for those who cry,those who hurt, those who have searched,and those who have tried,for only they can appreciate the importance of people who have touched their lives.Love begins with a smile,grows with a kiss and ends with a tear.The brightest future will always be based on a forgotten past, you can't go on well in life until you let go of your past failures and heartaches. When you were born,you were crying and everyone around you was smiling. Live your life so that when you die,you're the one who is smiling and everyone around you is crying. Please send this message to those people who mean something to you, to those who have touched your life in one way or another,to those who make you smile when you really need it,to those that make you see the brighter side of things when you are really down,to those who you want to let them know that you appreciate their friendship.And if you don't, don't worry,nothing bad will happen to you,you will just miss out on the opportunity to brighten someone's day with this message.` //調用功能 wordCounterV1(str) }
