Impact factor of a scientific journal is a measure reflecting the average number
of citations to articles published in science journals. For this task we are using a
simplified formula for calculating the impact factor:
`text{Total sum of all citations articles published in the journal received}/text{Total number of articles published}`
Rounding is always preformed up. For example the impact factor of the
“Journal for ore research and time wasting” that published 38 articles quoted
894 times is 894 / 38 = 23.53 rounding up to 24.
You are the editor of one scientific journal. You know how much article you are
going to publish and the owners are pushing you to reach a specific impact
factor. You are wondering how many scientists you will have to bribe to cite
your article to meet the owners demands. Since money is tight you want to
bribe the minimal amount of scientists.
First and only line of input will contain 2 integers, `A` (`1\ ≤\ A\ ≤\ 100`), number of
articles you plan to publish and `I` (`1\ ≤\ \ I\ \ ≤\ 100`) impact factor the owners
require.
First and only line of output should contain one integer, the minimal number
of scientists you need to bribe.
