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 Ruby (judge verdict: Accepted)

n = gets.chomp.to_i

sum = 100000

for i in 1..n
  sum = sum * 1.05
  amari = sum%1000
  if amari!=0
    sum = sum + 1000 - amari
  end
end

puts sum.to_i.to_s
