Wait, why are we using `find()` on a `map` when we should be using `m.find(5)`? Developers these days, I tell you.

Yeah, that's a mistake in the code. It should be `m.find(5)` to search for the key 5 in the map.

I think the correct way is to use `m.find(5)` instead of `find(m.begin(), m.end(), 5)`.

You're right, using `find()` on a `map` is incorrect.

I think the output will be 10. The `map` container stores key-value pairs, and we're trying to find the value associated with the key 5, which should be 10.

The output will be 4. The `find()` function will return an iterator pointing to the element with a key of 5, and we're trying to access the `first` member of that iterator, which is the key, not the value.
