Answer:
D. Maintain a count of queue items.
Explanation:
For checking the full condition of a queue you have to check whether the number of elements in the array are equal to the size of the array.If they are equal then we can that the queue is full.
Checking frontindex equal to backindex is for checking if the queue is empty.
In option C we have to check for arrayFullException but it will not be a good approach.
So we conclude by saying that the answer is option D.

A file with the POTX file extension is a Microsoft PowerPoint Open XML Template file used to maintain the same layout, text, styles, and formatting across multiple PPTX files.
Answer:
The solution code is written in Python 3:
- import keyword
-
- def checkValidVariable(string):
- if(not keyword.iskeyword(string)):
- return True
- else:
- return False
-
- print(checkValidVariable("ABC"))
- print(checkValidVariable("assert"))
Explanation:
Firstly, we need to import keyword module so that we can use its iskeyword method to check if a string is registered as Python keyword (Line 1).
Next, we create a function checkValidVariable that takes one input string (Line 3). Within the function body, we use iskeyword method to check if the input string is keyword. Please note the "not" operator is used here. So, if iskeyword return True, the True value will be turned to False by the "not" operator or vice versa (Line 4-5).
We test the function by passing two input string (Line 9-10) and we shall get the sample output as follows:
True
False
