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)

debt = 100000

n = STDIN.gets.chomp!.to_i

n.times do
  debt *= 1.05
  if debt % 1000 != 0 then
    debt = ((debt / 1000).to_i+1) * 1000
  else
    debt = debt.to_i
  end
end

puts debt.to_i
