### Background

Everyone making translations from English to Russian knows an English phrase "Naked conductor runs along the bus". It has two very different meanings.

### Problem

Every bus in the Ekaterinburg city has a special man (or woman) called
conductor. When you ride the bus, you have to give money to the conductor.
We know that there are more than *P*% conductors and less than *Q*% conductors of all citizens of Ekaterinburg. Your task is to determine a minimal possible number of Ekaterinburg citizens.
By percentage, we know that there are more than P% conductors and less than Q% conductors of all Russian citizens in this city

### Input

Two numbers *P*,*Q* such that 0.01 ≤ *P*, *Q* ≤ 99.99. Numbers are given with 2 digits precision. These numbers are separated by some spaces or "end of line" symbols.

### Output

The minimal number of Ekaterinburg citizens.

### Sample

### Notes

If there are 15 citizens and 2 conductors among them in Ekaterinburg, then
there are 13 1/3 % conductors of all citizens.
