Problem:
Debt Hell

Your friend who lives in undisclosed country is involved in debt. He is borrowing 100,000-yen from a loan shark. The loan shark adds 5% interest of the debt and rounds it to the nearest 1,000 above week by week.

Write a program which computes the amount of the debt in n weeks.

Input

An integer n (0 ≤ n ≤ 100) is given in a line.

Output

Print the amout of the debt in a line.

Sample Input

5

Output for the Sample Input

130000

Solution in JAVA (judge verdict: Wrong Answer)

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.math.BigDecimal;

public class Main {


	public static void main(String[] args) throws IOException {
		// 宣言
		BigDecimal shakkin = new BigDecimal(100000);
		BigDecimal taxper = new BigDecimal(0.05);
		BigDecimal rishi;
		int output = 0;

		// 文字列の入力
		BufferedReader input = new BufferedReader(new InputStreamReader(System.in), 1);
		System.out.println("何週間ですか?");
		int week = Integer.parseInt(input.readLine());

		if (week >= 100) {
			System.out.println("100以上は入力できません");
		}

		for (int i = 0; i <= week; i++) {
			// 5%の利子を計算する
			rishi = shakkin.multiply(taxper);
			// 5%の利子を元金に足す
			shakkin = shakkin.add(rishi);
		}
		// 1000円未満を切り上げる
		output = shakkin.setScale(-3, BigDecimal.ROUND_UP).intValue();
		System.out.println(output);
	}
