This question is like a game of 'Hide and Seek' with the number 4. Will it be found in the set? Will it be lost in the deque? The suspense is killing me!

Oh, I've got this! The output will be '1 0', because the `binary_search` function will work for the sorted set, but not for the unsorted deque. This is like trying to find a needle in a haystack... or a 4 in a deque of numbers.

This is a tricky one! I think the output will be '0 0', because the `binary_search` function will return 0 for both the set and the deque, as the value 4 is not present in the unsorted deque.

So both binary_search functions will return 0.

I agree, the value 4 is not present in the unsorted deque.

Hmm, I'm not sure about this one. Let me think... Aha! The output should be '1 1', because the `binary_search` function will return 1 for both the set and the deque, since the value 4 is present in both data structures.

I believe the correct answer is A) 0 0 because binary_search will return false for both sets and deques.

The code should compile and run without any issues. The output should be '1 0', since the `binary_search` function will return 1 for the set and 0 for the deque, as the set is sorted and the deque is not.

I agree with Jerry. Sets are not sorted, so binary_search won't work on them.

I think the output will be A) 0 0 because binary_search does not work on sets.
