 # Birthday odddays

Here is an interesting factoid: “On the planet Earth, if there are at least 23 people in a room,
the chance that two of them have the same birthday is greater than 50%.”
You would like to come up with more factoids of this form.

Given two integers (minOdds and daysInYear), your method should return the fewest number of people (from a planet where there are daysInYear days in each year) needed such that you can be at least minOdds% sure that two of the people have the same birthday. See example 0 for further information
Given 2 integers A and B.

Return the fewest number of people (from a planet where there are B days in each year) needed such that you can be at least A percent sure that two of the people have the same birthday.

See example 1 for further information

Input Format

``````The first argument given is the integer A.
The second argument given is the integer B.

Output Format

``````Return the fewest number of people (from a planet where there are B days in each year) needed such that you can be at least A percent sure that two of the people have the same birthday.
``````

Constraints

``````1 <= A <= 99
1 <= B <= 10000
``````

For Example

``````Example Input 1:
A = 75
B = 5
Example Output 1:
4
Example Explanation 1:
We must be 75% sure that at least two of the people in the room have the same birthday. This is equivalent to saying that the odds of everyone having different birthdays is 25% or less.

1.If there is only one person in the room, the odds are 5/5 or 100% that nobody shares a birthday.

2.If there are two people in the room, the odds are 5/5 * 4/5 = 80% that nobody shares a birthday. This is because the second person has 4 "safe" days on which his birthday could fall, out of 5 possible days in the year.

3.If there are three people in the room, the odds of no overlap are 5/5 * 4/5 * 3/5 = 48%.

4.If there are four people in the room, the odds are 5/5 * 4/5 * 3/5 * 2/5 = 19.2%. This means that you can be (100% - 19.2%) = 80.8% sure that two or more of them do, in fact, have the same birthday.

We only need to be 75% sure of this, which was untrue for three people but true for four. Therefore, your method should return 4.

Input 2:
A = 50
B = 365
Output 2:
23
