Either both or neither of x and y should be given

Either Both or Neither of ‘x’ and ‘y’ Should be Given:

When dealing with the condition “either both or neither of ‘x’ and ‘y’ should be given”, it means that both variables ‘x’ and ‘y’ must be provided or neither should be provided. Let’s explain this condition in detail with a few examples:

Example 1:

In this example, ‘x’ and ‘y’ are both given:

Input:
x = 5
y = 10

Output:
Both 'x' and 'y' are provided.

Example 2:

In this example, neither ‘x’ nor ‘y’ is given:

Input:
x = null
y = null

Output:
Neither 'x' nor 'y' is provided.

Example 3:

In this example, only ‘x’ is given:

Input:
x = 7
y = null

Output:
Invalid input. Either provide values for both 'x' and 'y' or for neither.

Example 4:

In this example, only ‘y’ is given:

Input:
x = null
y = 15

Output:
Invalid input. Either provide values for both 'x' and 'y' or for neither.

By adhering to the condition “either both or neither of ‘x’ and ‘y’ should be given”, you ensure that the input follows the specified rule, indicating whether both ‘x’ and ‘y’ are provided or neither of them are.
