Read a year.
Output Format:
Print whether the year is leap or not.
Test Cases:
Input:
1900
Output:
Not a leap year

Question : 3
Program to find all possible permutations in which 'n' people can occupy 'r' seats in a theater is
discussed here.
N friends are planning to go to a movie. One among them suggested few movies and all others started
to discuss and finally they selected a movie. One among them quickly booked their tickets online, to
their surprise they are unable to select their seats. All of them got confused. Then anyhow, decided to
go to the movie. They rushed to reach the theater on time. Again they are surprised that no one was
there in the theater. They are the only people about to watch the movie. There is 'r' number of seats
in which, 'n' number persons should sit. In how many ways they can sit inside the theater?
Given the number of people 'n' and the number of seats 'r' as input. The task is to find the different
number of ways in which 'n' number of people can be seated in those 'r' number of seats.

Question : 3
For example,
Input:
Number of people: 5
Number of Rows: 3
Output:
The total number of ways in which 'n' people can be seated in 'r' seats = 60.
Calculation:
P(n,r) =P(5,3)
=5! /(5?3)! = 5! / ( 5 ? 3 )!
= 120 / 2 = 60

Question:4
Write a program to implement a bubble sort algorithm for sorting the elements of an array.
Input Format:

The second line corresponds to the elements.
Output Format:
Print the element in ascending order.
Sample Input:
6
11 15 26 38 9 10
Sample Output:
9 10 11 15 26 38
