Data manipulation problem study resources

Wed, 28 Aug 2019 12:53:53 +0000

A colleague of mine is studying for tech roles, and they're asked to solve a consistent type of problem during the phone screenings: practicing manipulating data (sets, hash tables/dictionaries, arrays/lists, strings). These questions aren’t necessarily difficult problems and tend to require very little logic, and tend to be more about having a good understanding of the data types (such as listed above). I've provided some examples in this link: https://imgur.com/a/ITVeVnr

So I'm wondering if there are resources to study these questions. They aren't really Leetcode questions or the kind of thing found on Reddit daily programmer, which is where I'm generally directed to most often in the time I've been asking all over. Even if it's a textbook, it would be incredibly handy. And to be clear, I'm not looking for like a hack or golden secret, just resources for studying. Thank you for any help!

What is the difference between a batch and an epoch in a Neural Network?

Both of the batch size and number of epochs are integer values and seem to do the same thing in Stochastic gradient descent. What are these two hyper-parameters of this learning algorithm?
