Here the main catch in the question is “one pass”. What does it mean? It means you get to traverse the list only once and there’s no coming back to a node once you’ve traversed it. But to calculate the middle element you will require the length of the entire LinkedList, right?
While following PEP 8 is not strictly required, it is considered to be a best practice in Python programming. Many Python projects, libraries, and frameworks have adopted PEP 8 as their coding standard, and many code editors and IDEs have built-in tools to help developers adhere to these gui...
This post will include the questions that are Python specific and I’ll post the Django question separately. How are arguments passed – by reference of by value? The short answer is “neither”, actually it is called “call by object” or “call by sharing”(you can checkherefor more in...

We will now define a function that takes in the model, the processor, the reference image, and the question that we want to ask and prints the final answer by the VQA model:def get_answer_blip(model, processor, image, question): """Answers the given question and handles all the ...
Why does the answer matter? Because if you want to check if a character is part of the English alphabet, one popular way is to see if it’s betweenAandz(65 and 122 on the ASCII chart). Checking the ASCII code works but is clumsy and easy to mess up in coding interviews, especially...
