Problem Statement

The consumption tax rate in the Republic of ARC is t percent, where t is a positive integer.
There is a shop called Seisu-ya (integer shop) there. It sells each positive integer A for A yen (Japanese currency) excluding tax, that is$, \left\lfloor\frac{100+t}{100}A\right\rfloor yen including tax. Here, \lfloor x\rfloor$ denotes the largest integer not greater than x for a real number x.
Although Seisu-ya sells every positive integer, there are some positive integer values that cannot be the tax-included price of an integer. Among those values, find the N-th smallest value.

Input

Input is given from Standard Input in the following format:
t N

Output

Print the answer.

Constraints

• $1\leq t\leq 50$
• $1\leq N\leq 10^{9}$

Sample Input 1

10 1

Sample Output 1

10

In this sample, the consumption tax rate is 10 percent.

• The integer 9 is sold for $\left\lfloor \frac{110}{100}\times 9\right\rfloor = \lfloor 9.9\rfloor = 9$ yen including tax.
• The integer 10 is sold for $\left\lfloor \frac{110}{100}\times 10\right\rfloor = \lfloor 11\rfloor = 11$ yen including tax.

From above, we can see that 10 is not the tax-included price of any integer, and this is the minimum such value.

Sample Input 2

3 5

Sample Output 2

171

If the consumption tax rate is 3 percent, the smallest values that cannot be the tax-included price of an integer are $34, 68, 102, 137, 171, \ldots$

Sample Input 3

1 1000000000

Sample Output 3
