Daffodil

Title: Output the number of all daffodils on the console

What is the number of daffodils?

• Daffodil is a three-digit number;

• The sum of the cubes of the ones, tens, and hundreds of the narcissus number is equal to the original number.

Analysis:

• Use a loop to traverse all three digits (starting at 100 and ending at 999);

• Get the value of each digit in the three-digit number before calculation;

• Take out each value in the three-digit number, calculate the cubic sum and combine it with the original value Compare;

• Output the number of daffodils.

Practice:

The code is as follows (example):

public class Demo1 {
    public static void main(String[] args) {
    //不爱生姜不吃醋
        //使用循环遍历所有的三位数（100开始到999结束）；

        for(int i=100;i<1000;i++){
            // 计算之前获取三位数中的每个位上的值；
            int ge=i%10;
            int shi=i/10%10;
            int bai=i/100%10;

            // 将三位数中的每个数值取出来，计算立方和并与原数值比较；
            if(ge*ge*ge+shi*shi*shi+bai*bai*bai == i){
                // 输出水仙花数。
                System.out.print(i+" ");
            }
        }
    }
}
