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))
}
