Go 字符串统计

统计字符串每个字符出现次数！

package main

import (
"fmt"
)

func WordCount(s string) map[string]int {
var word string
m := make(map[string]int)
for i := 0; i < len(s); {
word = s[i : i+1]
fmt.Println(word)
v, ok := m[word]
if ok != false {
m[word] = v + 1
} else {
m[word] = 1
}
i += 1
}
return m
}

func main() {
    var str = "stringsg"
    fmt.Println(WordCount(str))
}
