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.
Yes, motion continues after forces are no longer being applied. Otherwise, a ball wouldn't continue to roll after it left your hand.
No, gravitational forces from every piece of matter in the universe affect every other piece of matter in the universe. Gravity cannot be blocked.
Answer:
- Transform binary or unary M:N relationship or associative entity with its own key.
Explanation:
Transform binary relation is described as the method through which a decimal can easily be converted into binary while the unary relationship is described as a relationship in which both the two participants occurs from the same entity.
In the given case, 'transform binary or unary M:N relationship' can be created using 'the primary key linked with the relationship plus any non-key aspects of the relationship and the primary keys of the related entities' as it displays the existence of a relationship between the occurrences of a similar set of the entity i.e. associative entity here.
Answer:
Following are the code to method calling
backwardsAlphabet(startingLetter); //calling method backwardsAlphabet
Output:
please find the attachment.
Explanation:
Working of program:
- In the given java code, a class "RecursiveCalls" is declared, inside the class, a method that is "backwardsAlphabet" is defined, this method accepts a char parameter that is "currLetter".
- In this method a conditional statement is used, if the block it will check input parameter value is 'a', then it will print value, otherwise, it will go to else section in this block it will use the recursive function that prints it's before value.
- In the main method, first, we create the scanner class object then defined a char variable "startingLetter", in this we input from the user and pass its value into the method that is "backwardsAlphabet".
