Takahashi has a deposit of 100 yen (the currency of Japan) in AtCoder Bank.  The bank pays an annual interest rate of 1 % compounded annually. (A fraction of less than one yen is discarded.)  Assuming that nothing other than the interest affects Takahashi's balance, in how many years does the balance reach X yen or above for the first time?
import math 
x=int(input())
ans= math.log(x/100)/math.log(1+0.01/1)
print(ans)
X = int(input())
s = 100
c = 0
while s < X:
  s = s + s  // 100
  c = c + 1
print(c)
