Here is one way to accomplish it.

The class with main method is below. A few notes about it. First, I made the Party class just an ArrayList of Hero objects, since I'm assuming that a party is just a collection of heroes. This makes asking names for each of the four heroes easier because we can loop through the party list.

Next, I moved the instantiation of the Hero objects into the initialization of the party so that the list already contains our Hero objects.

I utilized a for-each loop to check and assign classes to each Hero and a while loop to redirect the user back if they entered an invalid class. I check whether the class is valid using the boolean validClass. The final output of running this is shown at the very bottom.

You can use template literals to create types like this, for example:

You can produce all the combinations using a cross join. For example:

You oculd store the letter and if the ltter is changing, add a new letter line.

select the users which either don't have a name or a description, or are missing a linkedin or facebook link (sociallinks.value), and return what fields they are missing

I would think two left joins:

There are several ways you can do this. By the looks of it you want this to be done via one command that can be run directly in the shell.

You can do this leveraging arrayFilters option within updateMany. See https://docs.mongodb.com/manual/reference/method/db.collection.updateMany/#std-label-updateMany-arrayFilters for further documentation on it.

For simplicity I won't leverage indices so the below command would iterate over all the documents in the collection. If you want to leverage an index you would just adjust the query portion of the updateMany

You don't need to use tf.distribute.Strategy unless you have TPUs or multiple CPUs/GPUs. See here. You can run this as standard Tensorflow code without a strategy.

Here is the general concept, given the things you have posted so far

Note that answering a question is much easier if you've provided this in your question beforehand!

You need to clear the ax at the beginning of update, besides I think this part
