Answer:
The solution code is written in Python:
- def add_spaces(s):
- if len(s) < 2:
- return s
- else:
- return s[0] + " " + add_spaces( s[1 : ] )
Explanation:
Recursive function is a function that will call itself within the same function.
Let create a function named add_spaces() that take one input string, s (Line 1).
Next, create an if condition to check if the length of the input string is less than 2 (this means if the string has only one character), return the current string (Line 2-3).
Otherwise, it should return the first character of string, s[0] concatenated with a single space " " and concatenated again with the return output from the recursive calling add_spaces() that take s[1: ] as input parameter (Line 4-5). Please note s[1: ] is an expression we get the substring of the current string from position 1 till the end of string.

Answer:
One to One Relationship
Explanation:
Given that in a computer systems analysis about an entity-relationship model, a one-to-one relationship is a form of cardinality that involves the relationship that exists between two different entities Y and Z, such that one element Y can only be associated with one element Z, or in the other way round.
Hence, the cardinality of the friend_of relationship set between two student entities in the student entity set should be: "One to One Relationship"
