golang入门程序004 — 求水仙花数

package main

import (
	"fmt"
)

// 判断n是不是水仙花数
func isDaffodil(n int) bool {
	if n < 100 || n > 999 {
		return false
	}

	first := n % 10
	second := (n / 10) % 10
	third := (n / 100) % 10
	if n == first * first * first + second * second * second + third * third * third {
		return true
	}
	return false
}

func main() {
	for i := 100; i < 1000; i++ {
		if isDaffodil(i) == true {
			fmt.Printf("%d is daffodil\n", i)
		}
	}
}

执行结果如下：
