Program to print the berth of given railway seat number
Given a railway seat number, the task is to check whether it is a valid seat number or not. Also print its berth type i.e lower berth, middle berth, upper berth, side lower berth, side upper berth as per the figure below.
Examples:
Input: 10
Output: middle berth
Input: 7
Output: side lower berth
Approach:
- Check if seat number is valid seat number or not(i.e in range of 1 to 72).
- if (seat_number % 8) equals 1 or 4, then berth is a lower berth
- if (seat_number % 8) equals 2 or 5, then berth is a middle berth
- if (seat_number % 8) equals 3 or 6, then berth is an upper berth
- if (seat_number % 8) equals 7, then berth is a side lower berth
- if (seat_number % 8) equals 0 then berth is a side upper berth
Below is the implementation of the above approach:

Output:
10 is middle berth 7 is side lower berth 0 invalid seat number
