go语言之给定英语文章统计单词数量(go语言小练习)
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：
packagemain
import(
"fmt"
"sort"
)
funcwordCounterV1(strstring){
/*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
fori:=0;i=65&&stringSlice[i]<=90)||(stringSlice[i]>=97&&stringSlice[i]<=122)){
temp=str[j:i]
iflen(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*/
fori:=rangewordStatistic{
iflen(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{
ifi[0]!='a'&&i[0]!='A'{
delete(wordStatistic,i)
}elseifi[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))
fori:=rangewordStatistic{
sortSlice=append(sortSlice,i)
}
sort.Strings(sortSlice)
/*输出结果*/
for_,v:=rangesortSlice{
fmt.Printf("%s:%d\n",v,wordStatistic[v])
}
fmt.Printf("wordcount:%d\n",len(wordStatistic))
}

wordCounterV1(str)
}
编译后终端输出结果：
