Starks Adventure in Python

Problem Statement:

House Stark of Winterfell is a Great House of Westeros and the royal house of the Kingdom of the North. Every once a year, the king offers 5 people from his kingdom a visit to this house. But there are certain conditions,

1. these 5 people should not be below or equal to 50. The group will be rejected if this condition is not satisfied for even a single person.
2. Each of the people is allowed to visit only one floor. The floor is decided on the basis of their age.
The remainder left after dividing the age by 5 will be the floor a person can visit.
3. If two or more person allotted the same floor, then only one person can get that floor, the rest will be allocated vacant floors.

Remember the indexing starts from 0.

Given the ages of 5 people, determine which floor each individual can visit.

Example:
Input1:
Enter the ages of 5 people:
54 57 53 59 59
Output1:
Age: 59, Floor: 0
Age: 59, Floor: 1
Age: 57, Floor: 2
Age: 53, Floor: 3
Age: 54, Floor: 4

Input2:
Enter the ages of 5 people:
51 52 53 50 54
Output2:
This group is rejected.
