给定一篇英语文章,要求统计出所有单词的个数,并按一定次序输出。思路是利用go语言的map类型,以每个单词作为关键字存储数量信息,代码实现如下:
package main
import (
"fmt"
"sort"
)
func wordCounterV1(str string) {
/*定义变量*/
stringSlice := str[:]
temp := str[:]
wordStatistic := make(map[string]int)
/*把所有出现的单词放入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
}
}
/*把首字母为大写的单词转换为小写;去除无效字符*/
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的关键字映射到string切片进行排序*/
sortSlice := make([]string, 0, len(wordStatistic))
for i := range wordStatistic {
sortSlice = append(sortSlice, i)
}
sort.Strings(sortSlice)
/*输出结果*/
for _, v := range sortSlice {
fmt.Printf("%s:%d\n", v, wordStatistic[v])
}
fmt.Printf("word count:%d\n", len(wordStatistic))
}
主函数随便输入一篇英语文章
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.`
//调用功能
wordCounterV1(str)
}
编译后终端输出结果:
