Golang/Go语言水仙花数

以下是多位水仙花数的Go语言方法

package main

import (
    "fmt"
    "math"
    "strconv"
    "time"
)
func main() {

    //水仙花数
    t1 := time.Now()
    var i int
    for i = 1; i < 99999999; i++ {
        var len1 int = len(strconv.Itoa(i))
        var len2 int = len(strconv.Itoa(i))
        var s [20]int
        var sum = 0
        for j := 0; j < len1; j++ {
            s[j] = i / int(math.Pow10(len1-j-1)) % 10
            sum = sum + int(math.Pow(float64(s[j]), float64(len2)))
        }

        if sum == i {
            fmt.Println(i)
        }
    }
    ttt := time.Since(t1)
    fmt.Println("耗时：",ttt)

}
