Queue in C is a data structure that is not like stack and one can relate the behavior of queue in real -life. Unlike stack which is opened from one end and closed at the other end which means one can enter the elements from one end only. Therefore, to overcome the scenario where we...
You can use thesizemember function to retrieve the number of elements in the queue object. The function has a constant time performance. #include<iostream>#include<queue>using std::cout;using std::endl;using std::queue;using std::string;intmain(){std::deque<string>deq1={"one","eight",...
Now, it is required that we access thedeque’s front without popping elements of adequefrom any direction. How can we do that? Let’s learn it below. Before discussing the solution, we must learn how indexing works in Python and how we can use indexes to our advantage to access the fr...

deque() << "\n"; return 0; } I can't think of a reason you'd implement a queue this way, as the queue grows in size deque gets more and more expensive, using the original code you'd ultimately end up with a stack overflow. If you need a queue use std::queue or std::...
Examples come later in this post. That’s a lot of useful information. Let’s look at the code example to use cProfile. Start by importing the package. # import module import cProfile 3. How to use cProfile ? cProfile provides a simple run() function which is sufficient for most ...

I'm generally not convinced that using Keras preprocessing functions outside of where they belong is the right approach. A simple way would be to usetf.image.random_crop. Assuming your image is larger than(200, 200, 3), you can just use this line: ...
