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?
X = int(input())
G = 100
after_year = 0

while X >= G:
    G = int(G * 1.01)
    after_year += 1

print(after_year)
X = int(input())
G = 100
after_year = 0

while X > G:
    G += G // 100
    after_year += 1

print(after_year)
