一、Description

Farmer John made a profit last year! He would like to invest it well but wonders how much money he will make. He knows the interest rate R (an integer between 0 and 20) that is compounded annually at his bank. He has an integer amount of money M in the range 100..1,000,000. He knows how many years Y (range: 0..400) he intends to invest the money in the bank. Help him learn how much money he will have in the future by compounding the interest for each year he saves. Print an integer answer without rounding. Answers for the test data are guaranteed to fit into a signed 32 bit integer.

Input

* Line 1: Three space-separated integers: R, M, and Y

Output

* Line 1: A single integer that is the number of dollars FJ will have after Y years.
二、題解
?????? 題目的提示很明顯，計(jì)算過程如下：
?INPUT DETAILS:
????? 5% annual interest, 5000 money, 4 years
OUTPUT DETAILS:
Year 1: 1.05 * 5000 = 5250
Year 2: 1.05 * 5250 = 5512.5
Year 3: 1.05 * 5512.50 = 5788.125
Year 4: 1.05 * 5788.125 = 6077.53125
The integer part of 6077.53125 is 6077.
???? 需要注意的是計(jì)算過程中間結(jié)果要用double存放。
三、java代碼
import java.util.Scanner;public class Main {public static void main(String[] args) { Scanner sc = new Scanner(System.in);int r,m,y,i;double result,r1;r=sc.nextInt();m=sc.nextInt();y=sc.nextInt();r1=0.01 * r+1;result=m;for(i=0;i<y;i++){result*=r1;}System.out.println((int)result);} }
